[Zope-dev] Big problem.

[Andrew T Sydelko]

Urgh! While trying to get Zope 2.5.0b3 working I accidentally
started a 2.5.0b3 ZEO client on a Zope 2.4.3 ZEO server.

Doing this caused some stuff (Sessions?) to be added to the 
database. When the live 2.4.3 ZEO client stopped, it wouldn't
restart with the following traceback:

------
2002-01-10T21:27:44 PANIC(300) z2 Startup exception
------
2002-01-10T21:27:44 ERROR(200) ZODB Couldn't load state for '\x00\x00\x00\x00\x00\x00\x00\x02'

Either I need to get 2.5.0b3 working (it was dying with Error Code 11
problems) or I need to figure out how to remove the things that
were added to the database by a 2.5.0b3 ZEO client.

Any help or insight would be greatly appreciated.
