[VW7.4.1] 100% CPU when connected to Store

Janko Mivšek
Dear Visualworkers,

I just migrated my development environment to 7.4.1. and now I have a
strange problem with Store: when connected my CPU goes to 100% and stays
there until I disconnect. I'm using Linux. Has anyone similar problems?

I tried to find some infinite loop with help of Process Monitor
unsuccessfully. Which process should be debugged for Store connection?

Thanks and best regards
Janko

We are at least two with exactely the same problem. No solution yet.
Have a look at the following thread on this list:
"[BUG] Unix VW7.4.1 sometimes runs hot"



Bye

My guess is to look around the network code for the
Store/PostgreSQL connection. Look for a tight loop
around a read/fill buffer which returns zero bytes read.
Anyway, that's just a will guess. Good luck.

Dear VisualWorkers,

I'm wondering if that problem is already solved and some patch exists
somewhere?

It seams that problem is not only with Store but with any TCP/IP
application. Many times my Swazoo (Aida/Web) server causes 100% CPU
burnout and it must be restarted. Many times, but not always. Because of
that 7.4.1 is practically useless for me until this problem is solved.

Best regards
Janko

You should have a look at the thread named: "[BUG] Unix VW7.4.1
sometimes runs hot" in this list.


Here are some quotes:

"
I've created AR#50994: "A remote Postgres connection makes the Linux VM
run hot" for this issue. Thanks to all who reported the problem.
"


"
Just a quick update on the progress. It seems that the bug was located
and squashed, it will however require a new VM build. The conclusion is
that it likely affects all Unix VMs, not just Linux. It's not clear to
me yet if this will be deemed enough to trigger a release of an official
bug fix VM at this point. It should make the 7.5 VMs at the latest though.

And in a different thread, re: setting environment variables in the Mac OS X Intel X11 VM.

I believe new engines that fix this problem, along with the VM using all
the CPU on socket connections (VW running hot) and another bug I can't
recall right now, will be available sometime over the next two weeks.

Please don't take that as a promise that they will be here in two weeks,
simply take it as a notice that internally we're moving forward with
releasing new engines soon.

Just a question: is this problem fixed now? Or is there a reliable  
workaround? I couldn't find any further messages about this bug.

Cheers,
Lukas

I have not confirmed it but the new VM patch apparently fixes this, see:

This problem is in the list of bugs fixed in the 7.4c engines, and since
I switched to 7.4c I haven't seen the problem, which I was seeing
multiple times a day previously.
