Hi there, 

we are running an zope system with one ZEO and six Zope Frontends

The system ist running for one Month without a problem under 

Today I had several errors in the zeo.log. 

2004-01-14T16:01:34 ERROR(200) Conflict Resolution Unexpected error
Traceback (most recent call last):
  File "/usr/local/www/Zope/lib/python/ZODB/ConflictResolution.py", line 109, in tryT
    old = state(self, oid, oldSerial, prfactory)
  File "/usr/local/www/Zope/lib/python/ZODB/ConflictResolution.py", line 38, in state
    p = p or self.loadSerial(oid, serial)
  File "/usr/local/www/Zope/lib/python/ZODB/FileStorage.py", line 712, in loadSerial
    raise POSKeyError(serial)
POSKeyError: 0000000000000000

Soon all fronends run out of service and this error is logged. 

I have rebuild the Data.fs with fsrecover.py. No Errors reported 
but its runnig again. But still some of the above errors are logged 
in zeo.log. 

Anybody some Idea what caused this failure.
