We are having with a memory issue with JBossCache replication (please see description attached below). We saw the posting in
http://jira.jboss.com/jira/browse/JGRP-33 and http://jira.jboss.com/jira/browse/JBCACHE-31. We are wondering if we are running into the same problem. What do you think? In http://jira.jboss.com/jira/browse/JBCACHE-31, Bela Ban indicated that the problem was not reproducible in JDK 1.5 (we are using JDK 1.4) and he is going to investigate this with JDK 1.4. Any progress in this issue yet? Thanks, Tim ================================================================================== Description of the problem: To summarize, this is what we did yesterday (after hooking up JProbe to crm_workflow_2): insert 2 objects to the samekey on crm_workflow (asynchronously replicated to crm_workflow_2) and retrieve them from crm_workflow_2 force garbage collection and take heapdumps insert another 100 objects to the samekey on crm_workflow and retrieve them from crm_workflow_2 force garbage collection and take heapdumps insert another 100 objects to the samekey on crm_workflow and retrieve them from crm_workflow_2 force garbage collection and take heapdumps insert another 100 objects to the samekey on crm_workflow and retrieve them from crm_workflow_2 force garbage collection and take heapdumps We observed around 9 MB ?leak? on both crm_workflow and crm_workflow_2, and JProbe indicated that it?s related to JGroups. The heapdumps taken confirmed that as well. Objects belonging to org/jgroups grew as more PUTs were invoked. The number of cached object inside the TreeCache remained only one per JVM. 2 PUT 102 PUT 202 PUT 302 PUT heap usage - crm_workflow 66,510,928 75,479,360 84,786,040 93,876,944 heap usage - crm_workflow_2 64,554,256 73,526,144 82,513,320 92,926,720 Number of org/jgroups/util/Queue (crm_workflow) 56 2,856 5,656 8,456 Number of org/jgroups/util/Queue (crm_workflow_2) 56 2,856 5,656 8,456 Number of org/jgroups/JChannel (crm_workflow) 2 102 202 302 Number of org/jgroups/JChannel (crm_workflow_2) 2 102 202 302 View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=3868649#3868649 Reply to the post : http://www.jboss.org/index.html?module=bb&op=posting&mode=reply&p=3868649 ------------------------------------------------------- SF email is sponsored by - The IT Product Guide Read honest & candid reviews on hundreds of IT Products from real users.
