[jboss-user] [Performance Tuning] - java.lang.OutOfMemoryError: Java heap space in JBoss Product

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? View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4139151#...
