It would help others to help you, if you gave info on what your platform / setup is, and when this error occured.

My understanding of database conflict errors is they occur when two processes fight with each other talking to the ZODB. One or more older versions of Zope had bugs that caused such errors, but that was a while back.

We recently had such database conflict errors when starting Zope. When I posted on the newsgroup, it was suggested I put a "sleep 10" between the 2 zope processes starting, so that one was fully up and running before the other one tried to start. I did that and have had no problems since. Maybe that would work for you.

In my ignorance I'm not 100% certain that such warnings always actually matter - it may be a problem that Zope complains about but can recover from. More knowledgable people might comment on that. Nevertheless, a good idea to get rid of warnings for its own sake.

Hope that helps,
