    GC running and making site down

    890256
      Hi ALL,

      We are using 32 bit linux machine and with the following JVM settings. GC is starting and stopping fine. But suddenly like after 10,12 hours GC is running continously and making application very slow.

      -Dprogram.name=run.sh
      -Dprogram.name=run.sh
      -Xms1524m
      -Xmx1524m
      -Dsun.rmi.dgc.client.gcInterval=3600000
      -Dsun.rmi.dgc.server.gcInterval=3600000
      -XX:NewSize=512m
      -XX:MaxNewSize=512m
      -Djava.net.preferIPv4Stack=true
      -XX:MaxPermSize=512m
      -XX:+UseConcMarkSweepGC
      -XX:+CMSClassUnloadingEnabled
      -Djavax.net.ssl.trustStore=/apps/prod/properties/.keystore
      -Djavax.net.ssl.trustStorePassword=changeit
      -Dcom.sun.management.jmxremote.port=8888
      -Djava.rmi.server.hostname=192.168.100.140
      -Dcom.sun.management.jmxremote.ssl=false
      -Dcom.sun.management.jmxremote
      -Xloggc:/apps/prod/gc.log
      -XX:+PrintGCTimeStamps
      -XX:+PrintGCDetails
      -Djava.net.preferIPv4Stack=true
      -Djava.endorsed.dirs=/apps/prod/jboss/lib/endorsed


      I know it may be one of the cause of memory leakage. We are analysing this as well. is there any configuration to make site stable until we find and clear the memory leakages?

      Can anyone suggest us anyway to resolve this.
