    java.lang.OutOfMemoryError: Java heap space in JBoss Product

    Anoop S Newbie

      Hi All,

      I have recently migrated my application in to JBoss Server and struggling a bit with performance tuning. I am getting java.lang.OutOfMemoryError: Java heap space exception in every three- four days. This is crashing the JBoss Server and i have to restart my server when this occurs.

      My heap setting in run.conf are

      if [ "x$JAVA_OPTS" = "x" ]; then
       JAVA_OPTS="-Xms1024m -Xmx2048m -Dsun.rmi.dgc.client.gcInterval=3600000 -Dsun.rmi.dgc.server.gcInterval=3600000"
      fi


      Can anybody suggest me a proper heap size? Do i have to set any other param along with this??

      Also can u suggest a good profiler for jboss?
