[Zope-dev] CoreSession, ZEO and BerkeleyStorage = CorruptedDataError

[Tony McDonald]

I'm pooped. I'll apologise in advance that there doesn't seem enough info.
In this email, but the setup is so complex that to put it all in would
exceed the mailing list message size :)  (and to tell the truth, I'm hoping
that someone can point a finger at a likely spot).

I really like CST, but if this doesn't work, I'm thinking about using
SQLSession as I'm really getting out of my depth here.

Any thoughts would be really appreciated.

I've got a ZEO system set up using this HowTo (which is very good BTW)
1) http://dev.zope.org/Members/dshaw/AdvancedSiteSetup

Then I installed BerkeleyStorage from a combination of
2) http://www.zope.org/Members/Duncan/BerkeleyStorage and
3) http://www.zope.org/Members/andyd/zopeberkeleydb

Then following the instructions at
4) http://www.zope.org/Members/randy/ZEO-Sessions

I set up a ZEO based CoreSessionTracking system and set up several client
zope systems (from (1)) and had them accessed 'randomly' using Apache
rewriterules.

I managed to get the system up and running. But once I 'invalidate' a
CoreSession, I get this error message;

Error Type: CorruptedDataError
Error Value: data_container/manage_container
