Hm. The bug report you sent is pretty much exactly what I'd expect when
hitting the Python Compiler stacksize bug. I suspect the problem here is
that Zope 2.4.3 provides it's own complete copy of the Compiler, so you're
not seeing Jeremy's fixes. Possible solutions:

  - wait for Zope 2.4.4
  - upgrade to the current CVS version of the Zope 2.4 branch, Zope-2_4-branch.
  This contains what will become (hopefully, shortly) 2.4.4. I'm assuming 
  there's a 2.4.4 planned.
  - upgrade to the current 2.5 beta.

I had faced similar problems ... try the following thread for help

  http://aspn.activestate.com/ASPN/Mail/Message/zope-Dev/940742

on how to trap the error on a running process.  For linux, you need
the command strace ... here is one url

  http://www.pugcentral.org/howto/truss.htm

Once you have the core file, you should invoke gdb like this ...

 gdb program core

where program is the path to the python executable and core is the
core file.  Then, type info threads to see which thread and where
the problem occured in zope/python.

[Zope-dev] Core dumps - How to find out the bug?

2002-01-20 Thread Dario Lopez-Kästen 

Hello!

I wonder what to do when zope coredumps?

I have been given the advice to hook up gdb to zope/python and see what
happens, but there are two problems with this:

1) I barely know gdb at all, let alone know how to hook it up to a running
process
2) The dumps happen at random (last one happened at 3 in the morning when a
co-worker was working from home).

I only have core dumps to work from. I include the stack from latest core
dump.

I am using python 2.1.2 (release), Zope2.4.3 release, RedHat Linux 7.2.
Python is compiled --without-pymalloc

What can I do more to track this down?

Thanks,

/dario
