Problem summary
****************************************************************
* USERS AFFECTED: WebSphere Application Server version 5 users *
* of Session Memory to Memory Persistence. *
****************************************************************
* PROBLEM DESCRIPTION: When Session Memory to Memory *
* Persistence is used, the meta data of *
* invalidated sessions are not removed *
* from Data Replication Service (DRS). *
****************************************************************
* RECOMMENDATION: *
****************************************************************
If users are using session memory to memory persistence, there
is a memory leak in session manager. The meta data of invalid
sessions are not removed from DRS and the leak is cumulative.
Problem conclusion
The memory leak is corrected by this fix.
Session Manager will make the DRS API calls to clean up the
meta data of invalid sessions stored in DRS tables.
The fix for this APAR is currently targeted for inclusion
in cumulative fixes 5.02.17 and 5.1.1.11.
