[ http://jira.jboss.com/jira/browse/JGRP-33?page=comments#action_12315953 ] James Wilson commented on JGRP-33: ----------------------------------
I am not sure that the test case provided actually demonstrates the issue (if there is one). The test case continuously sends messages via a JChannel instance, but it never calls the "receive" method on the channel instance, so the queue of messages to be "received" will grow forever. While this definitely increases the size of the heap, I think that this is a misuse of JChannel, not a bug. > 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 & SUN JDK 1.5.0 on Windows & Unix platforms > Reporter: B.S.Navin > Assignee: Bela Ban > Priority: Critical > Fix For: 2.2.8 > 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. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://jira.jboss.com/jira/secure/Administrators.jspa - If you want more information on JIRA, or have a bug to report see: http://www.atlassian.com/software/jira ------------------------------------------------------- SF email is sponsored by - The IT Product Guide Read honest & candid reviews on hundreds of IT Products from real users.
