Hello,
We have sometimes Tomcat (5.x) who consume all the CPU (or 50 %) of the CPU constantly in our productions servers (Linux or Windows). Our applications aren't doing anything and the only solution is to restart Tomcat. I don't know if the problem is related to Tomcat or to the JVM (Sun) but I suspect that can occur when all the physical memory of the server is used. However, we set heap (between 1GO and 2GO) like this: Xmx = Xms < [physical memory available] when the server starts, so Tomcat shouldn't have disk swapping problem. (Am I wrong?) But other services can eat the memory and the server can begin to swap... Does anyone has had a problem like this? Thank you. Benjamin
