Performance Issue with JBOSS 4.2.0.GA

[vethadas]

We have spring web application with JBOSS 4.2.0GA. All the request are coming through Apache server. JVM Settings - JAVA_OPTS="-Xms2048m -Xmx2048m -XX:+UseLargePages -Dsun.rmi.dgc.client.gcInterval=3600000 -Dsun.rmi.dgc.server.gcInterval=3600000".

In the Linux server after 2 days CPU utilization is 99.9% and Mem also full. And the application hangs. We need to restart JBOSS every 2 days. Anyone face similar issue. Please suggest some idea for performance tuning of JBOSS.

I advice you to try this solution.
Install two Jboss in cluster.

I suggest reading through some of the other posts in this forum because similar questions have been posted by others.

My guess would be that your application has a memory leak and when the heap fills up you are going into constant garbage collection mode. No amount of JBossAS tuning will help fix that.
