B.S.Navin updated JGRP-33:
--------------------------
Attachment: fc-fast-udp.xml
fc-fast-udp-tcpping.xml
Configuration files used for UDP/PING & UDP/TCPPING
> JGroups throws OutOfMemoryError after running for a few hours
> -------------------------------------------------------------
>
> Key: JGRP-33
> URL: http://jira.jboss.com/jira/browse/JGRP-33
> Project: JGroups
> Type: Bug
> Versions: 2.2.8
> Environment: SUN JDK 1.4.2_05
> Reporter: B.S.Navin
> Assignee: Bela Ban
> Priority: Critical
> Attachments: JGroupsMemTest.java, PublishThread2.java,
> fc-fast-udp-tcpping.xml, fc-fast-udp.xml, runj10.sh
>
>
> I ran 10 instances of a simple program with 3 threads. The max memory is kept
> as the JVM default (64M). The 10 programs join the same JGroup and the
> threads in the programs keep publishing a small hashmap at 5 second intervals.
> The heap memory consumed (Runtime.totalMemory() - Runtime.freeMemory())
> slowly increases over a period of 4-5 hours and reaches the default max limit
> (64M) when it starts throwing OutOfMemory errors on all instances.
> I have run the program on unix and windows machines with 1G RAM.
> Not able to make much from an HProf output of one of the instances.
> This seems to be the cause for the JBossCache bug
> "http://jira.jboss.com/jira/browse/JBCACHE-31"; too.
> I have tried out a UDP/PING and a UDP/TCPPING combination and this problem
> occurs in both cases.
