Tomcat sucks up 3GB+ RAM and 53% CPU (today) and cripples the MidTier. Restart Tomcat and all is fine for 2 days. Unacceptable to our 200 IT users and is killing us. Our base of 4800 end users touches Remedy via our Kinetic front end, which is never an issue; just the MidTier for IT Staff. Any help is much appreciated !!!! Specifics: We are running Tomcat for ARS and Tomcat for Kinetic, as separate services. The ARS Tomcat runs away with Memory and cripples us at 3GB, while CPU is fine with its service. Kinetic's Tomcat is fine.
