Download Description
PQ97151 resolves the following problem:

PROBLEM SUMMARY:

USERS AFFECTED:
All users of WebSphere Application Server using HTTP Session memory-to-memory replication or Dynamic Cache replication.

PROBLEM DESCRIPTION:
Application Server hangs from a deadlock during a replication service reset.

RECOMMENDATION:
While using the replication service and a replicator reset occurs, a deadlock could occur, causing the Application Server to hang. A javacore may be produced as well.

PROBLEM CONCLUSION:
Additional checks were put in place to avoid the deadlock situation when a reset occurs. This fix should be available as a part of 5.1.1 cumulative fix 3 and potentially 5.0.2 cumulative fix 10
