I have a webapp that runs an external process to do some processing. When that's running I have an extra "tomcat" process listed when I do a ps. It's not really tomcat, but something about the way that the JVM forks processes makes it look like it's another tomcat. When the processes finishes the extra "tomcat" goes away and I'm back down to one. It could be that you've got something simliar going on in the webapp(s) that you're running.

I agree about the need for "detective work", just hoping to discover the known areas where Tomcat can be expected to spawn new processes (and set up test cases to examine those first). In the short-term I'll probably add a log stmt or two directly to startup.sh / catalina.sh to either catch the invocation or rule that out. By the way, the only interesting thing I've found so far is that it appears during periods of heavy load (%CPU-wise). --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
