memory leak and high thread usage for my application

jerishsunny Sep 23, 2010 5:50 AM

hi All,

I am using jboss3.2.1 and java 1.4.2.13.my database is oracle 9.2. I am having ejb , hibernate and jdbc connections with my database.

I have my app & DB installed in hp -ux 11.23 ia64.

my run.conf setting are JAVA_OPTS="-server -Xss704k -Xms1024m -Xmx2048m -XX:MaxPermSize=256m -Xloggc:/var/opt/TnDM/mem_leak/GCLogFile.log -XX:+PrintGCDetails -Dsun.rmi.dgc.client.gcInterval=600000 -Dsun.rmi.dgc.server.gcInterval=600000 -XX:+HeapDumpOnCtrlBreak "

The threads supported my application is 520 and the application is stalled when it reaches this value.

Memory also keeps on rising and we require a restart every 10 days. on analysing the heap dump 96% of memory is used by org.jboss.resource.adapter.jdbc.local.LocalManagedConnection

kindly let me know a way forward

JBoss AS 3.2.1? That's 8 years old! If you cannot move up to AS 5.1.0, then could you at least try 3.2.8.SP1? At least that version is only 4 years old - perhaps it already has this problem fixed.

If I remember correct I have also problems with JDBC connection manager (long time ago ;-) with JBoss 3.2 version.
Most of the problems are solved with 4.0 or 4.2.
I recommend to upgrade to the latest 4.2 or 4.3 most difference is JBossMQ vs. JBossMessaging).
With JBoss5 you might come in trouble with such old application (depended to your app).
