Receiving the following (over and over): [GC 2515286K->2130638K(5238528K), 0.0748890 secs] | [GC 2515406K->2137619K(5237440K), 0.0824530 secs] | [GC 2521619K->2144601K(5237312K), 0.0933110 secs] | [GC 2528601K->2151535K(5236608K), 0.0912180 secs] | [GC 2533231K->2151543K(5237120K), 0.0885810 secs] | Using the settings you suggested: | JAVA_OPTS="$JAVA_OPTS -Xms5g -Xmx5g -XX:MaxNewSize=384m -XX:NewSize=384m -XX:Per | mSize=512m -XX:MaxPermSize=1g -Dsun.rmi.dgc.client.gcInterval=3600000 -Dsun.rmi. | dgc.server.gcInterval=3600000 -Djava.awt.headless=true -d64 -verbose:gc" | After some time, the CPU was sticking around 50% (even when there was no activity) then during the time above it rose to 75% and seems to be stuck there...see JConsole output here: http://www.allstarconsultants.com/jconsole1.jpg Any further help would be appreciated :-/ View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4137750#...
