PermGen problems with Lift and Jetty

Question

I\'m developing on the standard Lift platform (maven and jetty). I\'m repeatedly (once every couple of days) getting this:

Exception in thread \"7048009@qtp-         


        

Answer 1

This is because of the reloading of classes as you suggested. If you are using lots of libraries etc. the sum of classes will rapidly grow for each restart. Try monitoring your jetty instance with VisualVM to get an overview of memory consumption when reloading.
