BlankHi, I am frequently recieving conflict errors like below in Zope logs. We have ZEO implemented with 2 Zope servers accessing the storage and even then its not minimizing . Could anyone suggest whats happening here that cause this error. Is my Apache configuration also needs to be looked for to fix this OR its an inherent ZOPE bug ------------------------------------------------------------------------------------------------------------ Exception Type ConflictError Exception Value database conflict error (oid 0x09, class Products.Transience.Transience.Increaser, serial this txn started with 0x036f460d13550f66 2007-07-27 17:17:04.531000, serial currently committed 0x036f460e67cca9dd 2007-07-27 17:18:24.328000) --------------------------------------------------------------------------------------------------------------- SuSon
Could anyone suggest whats happening here that cause this error. Look at list archives.
You may try to incerase session-resolution-seconds to 300 in your instances zope.conf and see if there is less of these errors. BTW. Zope-DB is about Zope and relational databases only. -- Maciej Wisniowski

Then I'd suggest having a good google and and read up on ConflictErrors. You likely have a problem with your app's design that is causing a ConflictError hotspot...

ZEO and multiple app servers, if anything, will increase the liklihood of conflict errors...

The short version is that two independent transactions are modifying the same object at the same time and so Zope doesn't know which modified version of the object it should store.

This has nothing to do with Apache.

Please don't cross post. The zope-db list has nothing to do with this problem anyway. cheers, Chris -- Simplistix - Content Management, Zope & Python Consulting - http://www.simplistix.co.uk
