Error description
The customer has the following configuration :

Two Nodes running on 5.0 with two servers on each node.
Mem to Mem Replication enabled on the Session Manager.
Two Servers  say ClientA and ClientB configured to run in the
Client
Only mode on the Session Manager  which serve the servlet
requests and
the other two servers say ServerA and ServerB configured to run
in the
Server Only Mode which serve as the session store.

Problem Description : User makes request  which is routed to
ClientA
and a session got created. ClientA was brought down and the
request fo
the same session was made by the user and the session was not
being
returned to Client B by the servers which function as the
session
ore.
This was was a bug in the DRS component and an unofficial fix
was sent
to the customer which got postive feedback. We need an APAR for
this
problem against the DRS component to release an official fix.
The
abstarct of the APAR needs to be "Mem to Mem Rep client / server
partial partitioning fix".
