(What part of 'below' wasn't clear to you?) You are setting -XX:MaxPermSize=3512M - it's too high. 'jmap -heap' will tell you how much PermGen you're actually using, try setting -XX:MaxPermSize=64M or whatever is appropriate. You still haven't said how much RAM you actually have available, so I will assume you have 1 Tomcat running on a server with 4Gb of RAM. You can set -Xmx=1024M to set the heap size to 1Gb. p -- [key:62590808]
