I am frequently recieving conflict errors like below in Zope logs. 


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...



We have ZEO implemented with 2 Zope servers accessing the storage and even then 
its not minimizing .


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



Could anyone suggest whats happening here that cause this error.


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.



Is my Apache configuration also needs to be looked for to fix this OR its an 
inherent ZOPE bug


This has nothing to do with Apache.

Please don't cross post. The zope-db list has nothing to do with this 
problem anyway.

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.
