Cause
Though the customer specified the follow options to try to enlarge the MaxPerSize, but it failed to pass to the JAVA VM because if the below "if" statement.
if [ "x$JAVA_OPTS" = "x" ]; then
#JAVA_OPTS="-Xms128m -Xmx512m -Dsun.rmi.dgc.client.gcInterval=3600000 -Dsun.rmi.dgc.server.gcInterval=3600000"
JAVA_OPTS="-Xms768m -Xmx768m -XX:PermSize=256m -XX:MaxPermSize=512m -Dsun.rmi.dgc.client.gcInterval=3600000 -Dsun.rmi.dgc.server.gcInterval=3600000"
fi
The reason is that we set a $JAVA_OPTS value when ITCAM installed. $JAVA_OPTS is not NULL any more, and "x$JAVA_OPTS" will not equal "x".So,the JAVA_OPTS
specified in the if block will not be performed. To pass the JAVA_OPTS to the JAVA VM correctly, we should move the JAVA_OPTS out of the "if" block as follows:
if [ "x$JAVA_OPTS" = "x" ]; then
#JAVA_OPTS="-Xms128m -Xmx512m -Dsun.rmi.dgc.client.gcInterval=3600000 -Dsun.rmi.dgc.server.gcInterval=3600000"
JAVA_OPTS="-Xms768m -Xmx768m -XX:PermSize=256m -XX:MaxPermSize=512m -Dsun.rmi.dgc.client.gcInterval=3600000 -Dsun.rmi.dgc.server.gcInterval=3600000"
fi
JAVA_OPTS="$JAVA_OPTS -Xms768m -Xmx768m -XX:PermSize=256m -XX:MaxPermSize=512m -Dsun.rmi.dgc.client.gcInterval=3600000 -Dsun.rmi.dgc.server.gcInterval=3600000"

Resolving The Problem
Edit the run.conf JBOSS file and move or add the #JAVA_OPTS="-Xms768m -Xmx768m -XX:PermSize=256m -XX:MaxPermSize=512m outside of the if statement as the below example shows. The JAVA_OPTS statement will not get picked up because of the if statement.
if [ "x$JAVA_OPTS" = "x" ]; then
#JAVA_OPTS="-Xms128m -Xmx512m -Dsun.rmi.dgc.client.gcInterval=3600000 -Dsun.rmi.dgc.server.gcInterval=3600000"
JAVA_OPTS="-Xms768m -Xmx768m -XX:PermSize=256m -XX:MaxPermSize=512m -Dsun.rmi.dgc.client.gcInterval=3600000 -Dsun.rmi.dgc.server.gcInterval=3600000"
fi
>========= Add the below JAVA_OPTS statement here >=================================
JAVA_OPTS="$JAVA_OPTS -Xms768m -Xmx768m -XX:PermSize=256m -XX:MaxPermSize=512m -Dsun.rmi.dgc.client.gcInterval=3600000 -Dsun.rmi.dgc.server.gcInterval=3600000"
In the run.conf file for JBOSS
