Pharo 6 / VM crashes

Volkert

Dear all,

from time to time i trying the lastest Pharo 6 (curl get.pharo.org/60+vm | bash) and i am always
a bit scarred about its stability. I mainly use Roassal and Athens and after a few minutes the VM crashes. The
the same happens with Pharo 5, but less often ... i am using Linux Ubuntu 16.04 ...

What is the best way to help you to improve the situation?

Hello,

The same happened to me about a week ago. Apparently, the latest 'stable' (Feb 22) version of VR has some compactor bug which makes it crash.

Try this:
curl get.pharo.org/60+vmLatest | bash
It should download the latest (Apr 18) VM, which works just fine.

Hi,

About the best way to help...

A reproducible case that we (VM developers) can reproduce easily is the best way to help. If we do not have a way to reproduce your bug, we cannot do anything about it. The best is an image which crashes immediately after start-up or a do-it that reliably crash the system, combined with all the version numbers (OS version, vm version, pharo version) or a crash dump file which includes all those version numbers.

Trying another version of Pharo (like 5 instead of 6 like you did) and the latest VM over the stable is another thing you can do. If you can prove that the bug comes from recent images or recent VMs it helps us as we know where to look (in the VM or in the image).

As Oleks said the bug you mentioned should be fixed in the latest VM. The latest VM will be promoted to stable in the incoming weeks for the Pharo 6 release. Sorry for the inconvenience.

Best,

this is correct :)
in particular, in linux we recommend to use curl get.pharo.org/60+vmTLatest (the threaded hearbeat)

The *known* buggy "stable-VM" really needs to be replaced ASAP.  I've counted half a dozen reports of people burnt by it and stability concerns can only discourage more people from testing Pharo 6 beta.  

The answer ever time has been to use vmLatest, so why not someone just log onto the files server and manually rename the current "-latest" to "-stable".  Don't take time to determine which "latest" is most stable.  Any seems a better choice than the VM with *known* compactor bug.  We need a stable-Pre-Release-VM for final beta testing.
