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
