Disable all of the auto reloading features of tomcat. The mem leak seems to be centered there. Or at least, I haven't had a OOME since I turned that stuff off.
You would need clustered sessions of some sort. They either need to be persisted across the network using filip's code (tomcat 5 has this in it) or you need to write your own session manager that persists session data to the DB. --Angus > -----Original Message----- > From: Derek Clarkson [mailto:[EMAIL PROTECTED] > Sent: Tuesday, March 16, 2004 1:32 AM > To: 'Tomcat Users List' > Subject: Load balancing for uptime > > > > Hi all, > We have an app written in a mix of JSP, servlets and > struts across 3 > instances of apache, tomcat and an RMI server.
