Hello Scott,

The problem was finally resolved. The culprit was that since we had 2
apache instances (on the same physical server) with different IP
addresses (127.0.0.1 and 127.0.0.2), we needed set
consistentAddress=false in the Sessions element.

So the load balancer on the front end was not a problem, and is
working fine now without any forced persistence.
