Hello, I've recently installed Python 2.3.4 and Zope 2.7.0 on FreeBSD 5.2 and moved my Data.fs over with no apparent problems (at first). Previously I was using Python 2.3.3, Zope 2.7.0, and FreeBSD 4.9 on a slightly slower machine. However, now Zope is crashing with a segmentation fault when I try to edit one of the largest Python scripts (19k) in my site. This is a script that I last edited on the old machine. It runs fine, displays fine in the management interface, but trying to save it causes Zope to crash. Searching online seems to indicate that I should have set a larger stack size for Python. I didn't install Python from the FreeBSD ports collection (for various reasons), but did it myself. Does the Python stack size sound like the problem? If it helps, gdb traceback gives me: (and I don't know what most of this means) #0 0x080729f3 in lookdict_string (mp=0x867e4f4, key=0x815b4e0, hash=435549560) at Objects/dictobject.c:316 #1 0x08073741 in PyDict_GetItem (op=0x867e4f4, key=0x815b4e0) at Objects/dictobject.c:498 #2 0x0805b3c0 in class_lookup (cp=0x868526c, name=0x815b4e0, pclass=0xbfaab088) at Objects/classobject.c:189 #3 0x0805b807 in instance_getattr2 (inst=0x904548c, name=0x815b4e0) at Objects/classobject.c:729 #4 0x08060c65 in instance_getattr1 (inst=0x904548c, name=0x815b4e0) at Objects/classobject.c:708 Any help is appreciated.
