Hello, I am having trouble with Zope 2.4.3 and Python 2.1.1 and a stack overflow problem. I have upped the maxthreads and per process (doubled) stack that Michael suggested on a previous message (http://lists.zope.org/pipermail/zope-dev/1999-November/002116.html), but that did not fix the problem. Python was compiled with threads, and the only test that failed was test_format. I saw some stuff on Google about Python 1.5 series and stack overflows with re ... could this problem be related? The exact error message is: Stack overflow: pid 1723, proc python, addr 0x140ed5fe8, pc 0x120062858 Any suggestions or help is appreciated.
