I am the maintainer of the Server nothing more. But you are helping me cause, now i have a response, and a prove that i am not the only that think this system can have a memory leak. About the memory leak, I am saying that, not from a hour, but from the Genesis time here. ehhehehe. --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
