Problem summary
****************************************************************
* USERS AFFECTED: All users of WebSphere Application Server *
* version 5 using dynacache *
****************************************************************
* PROBLEM DESCRIPTION: Application servers hang when *
* replicating a non-serializable id. *
****************************************************************
* RECOMMENDATION: *
****************************************************************
Application servers hang when replicating a non-serializable
id. This is because the InvalidationAuditDaemono does not
cleanly recover from an exception situation.
Problem conclusion
This APAR prevents the dynacache from holding on to a lock. As
a result, the application server does not hang when replcating
a non-serializable id.
The fix for this APAR is currently targeted for inclusion in
fixpack 5.0.2.13 and 5.1.1.6. Please refer to the recommended
