As Chuck pointed out, find out what's causing the leak.

Some commands that might help include:

This command will print the PermGen memory usage in MB:
${JRE_HOME}//bin/jstat -gcold ${TOMCAT_PID} | /usr/bin/tail -1 | awk -F' '
'{print $2/1024}'

This command will give you a helpful snapshot of what's occupying PermGen:
${JRE_HOME}/bin/jmap -permstat ${TOMCAT_PID}

Thanks,
