[Zope] error in trace

Greetings, If anyone has experience with this error before, could you possibly steer me in a direction: 2001-09-18T10:26:38 ERROR(200) ZODB Couldn't load state for '\x00\x00\x00\x00\x00\x00 \x18' Traceback (innermost last): File /var/Zope240/lib/python/ZODB/Connection.py, line 519, in setstate AttributeError: 'None' object has no attribute 'load' My Zope 240 on RH7.1 with Python2.1.1 restarts often, and the trick about -without-pymalloc didn't seem to help. The above traceback I get most of the time when it restarts (not always). Many thanks for any help, Paul Zwarts
