How do you fix a PermGen error?
To fix it, increase the PermGen memory settings by using the following Java VM options. -XX:PermSize – Set initial PermGen Size. -XX:MaxPermSize – Set the maximum PermGen Size. In the next step, we will show you how to set the VM options in Tomcat, under Windows and Linux environment.
