RE: OutOfMemory:PermGen with Tomcat App Server
Hi All,
The attached Servlet code is causing for a permgen leak. It appears to me that this is due to Tomcat bug, the same issue is not seen with other application servers. Any help in resolving this issue is greatly appreciated.
I have also noticed in many other incidents in my code where AccessController.doPrivileged() is causing for Permgen memory leak. Anyways to get around/fix this problem.
Thanks,
Nagaraja
