Abstract

Out of memory seen when multiple users are logged-in in jsf portlet application

Download Description

PI73401 resolves the following problem:

ERROR DESCRIPTION:
Multiple users access the JSF Portlet application and after
some time we see out of memory exceptions as JVM heap continues
to grow

LOCAL FIX:

PROBLEM SUMMARY

USERS AFFECTED:
All users of IBM WebSphere Application
Server

PROBLEM DESCRIPTION:
While running JSF portlet
applications by many users, an OOM is
seen and session data gets lost

RECOMMENDATION:

When many users access JSF Portlet application concurrently,
session data gets mixed up and lost. Also during peak usage,
an OutofMemory error is encountered in the JVM heap which
requires a JVM restart.

PROBLEM CONCLUSION:
Code was modified to correctly handle concurrent session data.
The fix for this APAR is currently targeted for inclusion in
fix pack 9.0.0.3. Please refer to the Recommended Updates
