Pharo image don't restart

dario trussardi
Ciao,

i have a Ubuntu system
  where i defined a Pharo 7.0 - 64bit image managed with PharoLauncher.

I work with it for a month and all work fine.

Now after a save the image the system begin unstabled.

When the mouse go on the windows summary bar ( at the bottom of the Pharo window ) the image go down.

The first time i can launch the same image from the PharoLauncher,

but after a new  image save ( the image go down ) i can't relaunch the image.

When i do the launch the pharoLauch shell report:



I have some important work in the image ( and i don't have a backup )

Some consideration?

Thanks,
Dario

Ben Coman
You don't mention that you rebooted, so just try that first.  

cheers -ben

P.S. Quick summary for others, the error is...

sorry but I do not understand what you mean.

In any case i rebooted the system. ( restart )

The PharoLauncher  launch command on the Pharo 7.0 -64development image  report the same error.

Thanks,

Yes, thats what I meant.  Always the easiest thing to try.

 I'm not in a position to diagnose the error, but perhaps help you recover your work.
In PharoLauncher, if you right-click on the image you are trying to launch,
then choose "Show in folder" then browse to "pharo-local/ombu-sessions"
and you should see some files.  If you create a fresh image and copy those to the same location there,
the go World menu > Tools > Code Changes and see if you find your work.
Check out the filters. Possibly useful...
* Show only latest changes
* Show only changes in this package

OK, i see the methods ..... ( i need to understand what i can do with these .....  )

But in the image i  have the  data base with real data...... and ......

Stupidly I lost the version that started with the launcher,

saving it on itself after it began to have problems......


Thanks,

Hi,

The problem seems to come from: "no room in eden for allocateSmallNewSpaceSlots:format:classIndex:"
Eden is a part of the heap where new objects are allocated.
Basically, it appears that Pharo cannot create objects any more.
You can get information about gc and eden space here: https://clementbera.wordpress.com/2017/03/12/tuning-the-pharo-garbage-collector/

Could you try to run your image in headless mode to see if it starts?
ex: 

I would try to start your image with a bigger size for the eden.
Clément recommends to do: Smalltalk vm parameterAt: 45 put: (Smalltalk vm parameterAt: 44) * 4.
but it means you need an image that is started …

You can also set it as an argument to the VM: --eden <size>[mk]

You could try with —eden 15207744 for example:
~/Documents/Pharo/vms/70-x64/Pharo.app/Contents/MacOS/Pharo --eden 15207744 ~/Documents/Pharo/images/Pharo\ 7.0\ -\ 64bit\ \(development\ version\)/Pharo\ 7.0\ -\ 64bit\ \(development\ version\).image

Christophe

After copy the pharoLauncher entry with the error into 
Pharo7.0-64DTRDevErr entry

i do this:

/opt/pharolauncher/pharo-vm$ ./pharo --eden 15207744 /home/party/Pharo/images/Pharo7.0-64DTRDevErr/Pharo7.0-64DTRDevErr.image

the shell report:

pthread_setschedparam failed: Operation not permitted

***** This VM uses a separate heartbeat thread to update its internal clock

and handle events.  For best operation, this thread should run at a
higher priority, however the VM was unable to change the priority.  The
effect is that heavily loaded systems may experience some latency
issues.  If this occurs, please create the appropriate configuration
file in /etc/security/limits.d/ as shown below:

cat <<END | sudo tee /etc/security/limits.d/pharo.conf
*      hard rtprio  2
*      soft rtprio  2
END

and report to the pharo mailing list whether this improves behaviour.

You will need to log out and log back in for the limits to take effect.
For more information please see
...........r3732#linux
Errore di segmentazione (core dump creato)

Any idea  about it?

The ***** message required some action ?

I need to configure some operating system value ?

Thanks,

Dario

P.S. I have to conclude that there is no solution?

Then there should be a crash.dmp file that includes a stack trace.  I’m surprised the VM exists by this path; I would expect  the system to retry the allocation with an old space allocation that should work.

So, Dario, please keep a copy of your image and changes.  And please email me the crash.dmp file.  Create a clean one by deleting it first and then running the system until it fails and exits.  Multiple exits append to the crash.dmp file so it can end up being quite large.

So you have a segmentation fault. It means the image tries to access a memory address outside the memory range of its process.

Do you also have a segmentation fault if you run the image without the eden parameter?

this message is just a warning. If you want to avoid it, just execute this as root:

As Eliot said, it could be useful to get the crash.dmp file and the PharoDebug.log file.

No without eden parameter the system report the basic error

The  crash.dmp  is not create.

( If i right do the command to create it :

From pharoLauncher i launch the corrupt image some time,
the  shell report the issue, but don't create the crash.dmp file).


For PharoDebug.log  i'm not in office, I'll check tomorrow.

Thanks,
Dario

Re: Pharo image don't restart

Some consideration:


At 12 December: 

I work all day with the image.

at: 19:xx  I save the image without any problem.

But after saved the image the system begin 
unstable.

 
When the mouse go on the windows summary bar ( at the bottom of the Pharo window ) the image crash.

Some time i can launch - relaunch the same image from the PharoLauncher ( the pharo run but was unstable )

at: 19:45 After reload the unstable image ( as mentioned above )

i do the save command ( 
saving it on itself )
and the system crash.

After this crash ( when i do the image save command ),

i have not been able to launch the image. I do not know the status of this image ( I call this 
corrupt
image )

At 13 December:

A) 
From pharoLauncher i launch the corrupt image some time,

the  shell report the issue, 


but don't create the crash.dmp file.


B) 
After copy the pharoLauncher corrupt image into 
Pharo7.0-64DTRDevErr entry

i do this:

/opt/pharolauncher/pharo-vm$ ./pharo --eden 15207744 /home/party/Pharo/images/Pharo7.0-64DTRDevErr/Pharo7.0-64DTRDevErr.image

the shell report:

pthread_setschedparam failed: Operation not permitted
This VM uses a separate heartbeat thread to update its internal clock
and handle events.  For best operation, this thread should run at a
higher priority, however the VM was unable to change the priority.  The
effect is that heavily loaded systems may experience some latency
issues.  If this occurs, please create the appropriate configuration
file in /etc/security/limits.d/ as shown below:

cat <<END | sudo tee /etc/security/limits.d/pharo.conf
*      hard rtprio  2
*      soft rtprio  2
END

and report to the pharo mailing list whether this improves behaviour.

You will need to log out and log back in for the limits to take effect.
For more information please see
...........r3732#linux
Errore di segmentazione (core dump creato)

C) i have a PharoDebug.log but has the size of 16MB.

How can I send it to you?

This is the status of the problematic.

Thanks,

Dario

Re: Pharo image don't restart

Some consideration:


At 12 December: 

I work all day with the image.

at: 19:xx  I save the image without any problem.

But after saved the image the system begin 
unstable.

 
When the mouse go on the windows summary bar ( at the bottom of the Pharo window ) the image crash.

Some time i can launch - relaunch the same image from the PharoLauncher ( the pharo run but was unstable )

at: 19:45 After reload the unstable image ( as mentioned above )

i do the save command ( 
saving it on itself )
and the system crash.

After this crash ( when i do the image save command ),

i have not been able to launch the image. I do not know the status of this image ( I call this 
corrupt
image )

At 13 December:

A) 
From pharoLauncher i launch the corrupt image some time,

the  shell report the issue, 
<errorePharo.txt>

but don't create the crash.dmp file.


B) 
After copy the pharoLauncher corrupt image into 
Pharo7.0-64DTRDevErr entry

i do this:

/opt/pharolauncher/pharo-vm$ ./pharo --eden 15207744 /home/party/Pharo/images/Pharo7.0-64DTRDevErr/Pharo7.0-64DTRDevErr.image

Re: Pharo image don't restart

demarey
I did not notice the link in the previous link. I got the PharoDebug.log file.
It is very big because there are a lot of traces there.

The last one is the following.
Does it correspond to your crash?
To be sure, you could rename this file and try to run again your image to see if we have logs.

C) i have a PharoDebug.log but has the size of 16MB.

How can I send it to you?

you can try something like https://wetransfer.com

can you download the PharoDebug.log 

from link into my previous email?

The PharoDebug.log.

You can view it?

Re: Pharo image don't restart

dario trussardi
Ciao,

I did not notice the link in the previous link. I got the PharoDebug.log file.
It is very big because there are a lot of traces there.

The last one is the following.
Does it correspond to your crash?

Yes,  12 December 2018 6:47.......... 6:xxx

it's the time when I started having problems

To be sure, you could rename this file and try to run again your image to see if we have logs.

OK.

I rename the file.

When i Launch the corrupt image the system don't create the new PharoDebug.log


As this point ( but maybe it happened even before )
when from PharoLauncher on the corrupt image

 i select the Show in folder menu option

the shell report:


(nautilus:17273): GLib-GIO-CRITICAL **: g_dbus_interface_skeleton_unexport: assertion 'interface_->priv->connections != NULL' failed

(nautilus:17273): GLib-GIO-CRITICAL **: g_dbus_interface_skeleton_unexport: assertion 'interface_->priv->connections != NULL' failed

Thanks,

Dario

P.S. In the /etc/sysctl.conf i add this entry ( can they somehow interfere? )
kernel.shmmax=6442450944
kernel.shmall=1572864

Hi Dario,

So you have a recursive doesNotUnderstand: error and the system is running out of memory.  The questions are where and why?  You can try and debug this further by running the VM with --trace=259, e.g.

pharo-vm/pharo --trace=259 my image.image

This will produce lots of output, eventually ending in an endless stream of doesNotUnderstand:'s.  So capture the first few megabytes of output (see e.g. head(1) ($ man head))

FYI
"traceFlags is a set of flags.
1 => print trace (if something below is selected)
2 => trace sends
4 => trace block activations
8 => trace interpreter primitives
16 => trace events (context switches, GCs, etc)
32 => trace stack overflow
64 => send breakpoint on implicit receiver (Newspeak VM only)
128 => check stack depth on send (simulation only)
256 => trace linked sends "

Alternatively you could use a debugger such as gdb and I can tell you how to put a breakpoint on doesNotUnderstand:

Some consideration:


At 12 December: 

I work all day with the image.

at: 19:xx  I save the image without any problem.

But after saved the image the system begin 
unstable.

 
When the mouse go on the windows summary bar ( at the bottom of the Pharo window ) the image crash.

Some time i can launch - relaunch the same image from the PharoLauncher ( the pharo run but was unstable )

at: 19:45 After reload the unstable image ( as mentioned above )

i do the save command ( 
saving it on itself )
and the system crash.

After this crash ( when i do the image save command ),

i have not been able to launch the image. I do not know the status of this image ( I call this 
corrupt
image )

At 13 December:

A) 
From pharoLauncher i launch the corrupt image some time,

the  shell report the issue, 

but don't create the crash.dmp file.


B) 
After copy the pharoLauncher corrupt image into 
Pharo7.0-64DTRDevErr entry

i do this:

/opt/pharolauncher/pharo-vm$ ./pharo --eden 15207744 /home/party/Pharo/images/Pharo7.0-64DTRDevErr/Pharo7.0-64DTRDevErr.image

the shell report:

pthread_setschedparam failed: Operation not permitted
This VM uses a separate heartbeat thread to update its internal clock
and handle events.  For best operation, this thread should run at a
higher priority, however the VM was unable to change the priority.  The
effect is that heavily loaded systems may experience some latency
issues.  If this occurs, please create the appropriate configuration
file in /etc/security/limits.d/ as shown below:

cat <<END | sudo tee /etc/security/limits.d/pharo.conf
*      hard rtprio  2
*      soft rtprio  2
END

and report to the pharo mailing list whether this improves behaviour.

You will need to log out and log back in for the limits to take effect.

This is the status of the problematic.

Ciao Eliot,


Hi Dario,

    if you look at the end of the PharoDebug.log you will see:

So you have a recursive doesNotUnderstand: error and the system is running out of memory.  The questions are where and why?  You can try and debug this further by running the VM with --trace=259, e.g.

pharo-vm/pharo --trace=259 my image.image

This will produce lots of output, eventually ending in an endless stream of doesNotUnderstand:'s.  So capture the first few megabytes of output (see e.g. head(1) ($ man head))

FYI
"traceFlags is a set of flags.
 1 => print trace (if something below is selected)
 2 => trace sends
 4 => trace block activations
 8 => trace interpreter primitives
 16 => trace events (context switches, GCs, etc)
 32 => trace stack overflow
 64 => send breakpoint on implicit receiver (Newspeak VM only)
128 => check stack depth on send (simulation only)
256 => trace linked sends "

Alternatively you could use a debugger such as gdb and I can tell you how to put a breakpoint on doesNotUnderstand:

I do this command:

party@party001:/opt/pharolauncher/pharo-vm$ ./pharo --trace=259 /home/party/Pharo/images/Pharo7.0-64DTRDevErr/Pharo7.0-64DTRDevErr.image

This is the output:

pthread_setschedparam failed: Operation not permitted
This VM uses a separate heartbeat thread to update its internal clock
and handle events.  For best operation, this thread should run at a
higher priority, however the VM was unable to change the priority.  The
effect is that heavily loaded systems may experience some latency
issues.  If this occurs, please create the appropriate configuration
file in /etc/security/limits.d/ as shown below:

cat <<END | sudo tee /etc/security/limits.d/pharo.conf
*      hard rtprio  2
*      soft rtprio  2
END

and report to the pharo mailing list whether this improves behaviour.

You will need to log out and log back in for the limits to take effect.

No :-).  Can you put your image and changes up anywhere I can get at them?  Or can you put them in a zip or tar archive and email them to me? I'm curious.
