Subject Tomcat High CPU consommation
Date Wed, 29 Jul 2009 08:58:14 GMT


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

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.
