Error description
Env:
WSAS 5.1.1.7
J2RE 1.4.2 IBM AIX build ca142-20050929a
AIX, version 5.2
When running Tivoli Monitor it is observed that DRSHttpSessCache
contains more session objects than are being used. Apparently,
unused session objects are not getting removed from
DRSHttpSessCache.
Local fix Problem summary
****************************************************************
* USERS AFFECTED: All users of WebSphere Application Server *
* using HTTP Session memory to memory or *
* Dynamic Cache replication with push *
* or push-pull sharing policy. *
****************************************************************
* PROBLEM DESCRIPTION: A memory leak occurs in the replication *
* service due to improper cleanup of *
* metadata during a remove. *
****************************************************************
* RECOMMENDATION: *
****************************************************************
When a consumer of the replication service issued a remove for
a previously replicated object, a hashmap containing metadata
would not be cleaned up properly. This would cause the map to
grow continuously.
Problem conclusion
The removal of the data was moved further down in the
execution path. Clean up occurs as expected at this point of
execution.
This fix for this APAR is targeted for inclusion in fixpack
5.0.2.17 and 5.1.1.11. Please refer to the Recommended Updates
