Troubleshooting Grails/Groovy memory leaks?

Question

I\'ve got a Grails application that does a fairly decent amount of domain object creation and destruction, and it seems to run out of PermGen space at a very, very rapid rat

Answer 1

If this happens after you hot redeploy your application several times you may be affected by this Grails bug. The Tomcat FAQ also has several possible causes for PermGen leaks.
