Hi All, We all know that ideally we should have no ConflictErrors happening in our apps, but of course, that's often not the case ;-) Firstup, some questions about what gets logged for ConflictErrors, here's a line from one of our event logs: 2005-11-17T08:00:27 INFO(0) ZODB conflict error at /some_uri (347 conflicts since startup at 2005-11-08T17:56:20) What is this telling me? Did the user actually see a ConflictError page? Or was this error successfully resolved? What object did this ConflictError occur on and/or how can I modify my our Zope instances to find out where the conflict was occurring? Now, when should the number of ConflictErrors logged in this way start to become worrying? I analysed the logs from our cluster and we're getting about 450 conflict errors in our busiest hours when the cluster of 8 ZEO clients is taking about 11,000 hits in that hour. Is this 'bad'? If so, where should I start to make things better? All feedback greatfully received, especially if people have been in similar situations... cheers, Chris -- Simplistix - Content Management, Zope & Python Consulting - http://www.simplistix.co.uk
