Re: [jetty-users] Stop Jetty and free classloader in perm memory
|
Hello Aurelien,
Maybe you can follow bellow directions to narrow which class causes the leak:
http://blogs.sun.com/fkieviet/entry/classloader_leaks_the_dreaded_java
http://blogs.sun.com/fkieviet/entry/how_to_fix_the_dreaded
I ran into this kind of problem in the past with tomcat, and all I
can say is that this is one of the most trickier and time consuming
issues. Probably it is caused by user code and not by app server code.
Good luck,
