I'm confused... where does BerkeleyStorage come in here? It appears that the data is being saved to a FileStorage named "SessionStorage". In any case, this is sort of besides the point... I unfortunately have no idea what the problem could be. CST does not use the ZODB in any particularly taxing way. About the best I can do is recommend that you try to put the ZEO server that serves the session data on another system and see if the errors continue. If they do, and the problem is reproducible, we can fix it. - C Tony McDonald wrote:
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
