Hi Mark, Thanks for your reply. I tried reading the change log. It appears that in Tomcat 6.0.20 there is a fix related to memory leak using SSL. What I am thinking is that if this is the issue with the Tomcat 6.0.18 or an issue with my application. Can you confirm if there is a memory leak issue exists in using SSL with tomcat 6.0.18 on Linux environment which similar to my problem? It helps me concentrate on upgrading the Tomcat in my production. Please let me know if you need any further details about my environment.
Thanks, Bala. -----Original Message----- From: Mark Thomas [mailto:ma...@apache.org] Sent: Wednesday, August 04, 2010 4:18 PM To: Tomcat Users List Subject: Re: Memory leak in using SSL with Tomcat 6.0.18 On 04/08/2010 10:49, B.
