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.
