[Zope] Strange errors preventing our Zope instance from starting

[Bruno Mattarollo]

Hello,

We are running a Zope 2.5.1 (yes, I know, old) version on one of our 
servers and yesterday we started getting these errors (quite a lot of 
them) on the error log:

2004-01-05T11:06:05 ERROR(200) ZODB Couldn't load state for 
'\x00\x00\x00\x00\x00y0s'
Traceback (innermost last):

POSKeyError: 0000000000793073

And then this:

So this morning we tried a "restart" and it didn't work, some python 
process was refusing to die, even with "kill -9" :( So we restarted the 
server and this is what we get now in the error log:

So, I think there is something strange here but I don't know what the 
issue might be. Any suggestion?

Cheers
