Hi, That's very interesting. We've been using tomcat for a couple of years now in production, on Solaris servers the whole time. Been using tomcat version 3.1.x through 4.1.x. Been using JDK 1.2.2 through 1.4.1RC. Been using Solaris 2.6 to 2.8.
We've never had a tomcat CPU usage problem, and we analyze it on an ongoing basis with top, truss, some in-house tools. Not saying you couldn't have one, but I'd be very curious whether your apps running on tomcat do anything while "idle".
