Hi Tim

Just been digging some more on this issue and found:
http://mail.zope.org/pipermail/zodb-checkins/2004-January/008063.html

In every case I get this error, the tid's are equal, which suggests your notes about the <= potentially being bad were correct ;-)

I'm low on fu here, so what's the problem with the two tid's being the same and do you have any idea why this could be occuring in production code on Zope 2.9.x?

cheers,

Chris

First time I've seen it, been running this instance on Zope 2.9.2 for about a month so far with no problems. But, never got this before ever with Zope 2.7.x...

cheers,

Chris
