I believe all the appropiate python stack patches are applied.

Hmmm. Maybe some FreeBSD patch will fix your problem. The current FreeBSD /usr/ports/lang/python21/files has the following files: -rw-r--r-- 1 root wheel 2820 Nov 14 2002 patch-Lib:os.py -rw-r--r-- 1 root wheel 326 Jan 16 2002 patch-Misc:Makefile.pre.in -rw-r--r-- 1 root wheel 688 Nov 14 2002 patch-Modules:Setup.dist -rw-r--r-- 1 root wheel 793 Feb 6 17:44 patch-Python-thread_pthread.h-stacksize -rw-r--r-- 1 root wheel 429 Oct 19 2001 patch-setup.py -rw-r--r-- 1 root wheel 599 Apr 13 21:20 zwiki.patch You might also check the following Zwiki threads on memory problems (all related to FreeBSD, but they may be caused by Imeme's memory limit) - http://webseitz.fluxent.com/wiki/ZwikiFreebsdStabilityProblems - http://zwiki.org/SiteReliability - http://www.zwiki.org/GeneralDiscussion Pieter cc: zwiki

"MemoryError" would mean you have run out of virtual memory. This may or may not be a Zope problem. Dieter

Its:

Zope 2.6.1 (source release, python 2.1, linux2) python 2.1.3 openbsd3

I believe all the appropiate python stack patches are applied.

In my experience, (at least on FreeBSD) it would simply fall over when it ran out of stack space, I don't remember ever seeing MemoryError. But I may not have been paying close enough attention ;^) Looks like its running out of memory when a BTree subobject is being loaded. Do you have any idea how much memory the process was using when you got the error? -Casey
