Hi, We experience incidental crashes with Zope 2.4.3 / Python 2.1.1. I've read that python 2.1.2 may fix this problem, and people who upgrade are advised to rebuild Zope as well. However, I have a rather custom Zope source tree. Is there a way to do a proper 'make clean' in the zope tree? Removing *.o *.pyc *.so *.pyo doesn't seem to do the trick - I end up with an even more unstable Zope (and very scary python stack frame errors). With regards, Ivo -- Drs.
