    Give it more memory? Apr 18, 2011 at 5:04
  • Thanks. we have given the heap size memory -Xms3000M -Xmx3000M, is that ok or do we need increase the memory? our RAM size is 7.6 GB. Apr 18, 2011 at 5:21
  • Could indicate a memory leak (i.e. a bug in the application that causes it to keep memory/objects around that should not be kept). Apr 18, 2011 at 7:31
  • You can increase the memory on the instance, I have a Jboss server running at -Xms2000M -Xmx6500M. I opt for the lower -Xms because spawned processes will take that as their initial memory footprint. It will cause issues if it is too high and you spawn sub processes.

I think you should enable JMX port on your JVM and run the Mission Control product to monitor the memory as your JVM runs. Using Mission Control, you should be able to see what the problem is.
