title: CPU Utilization at 100% with Tomcat 7.0
body: <p>We have a WinTel server with 4 CPU's, 8GB of RAM, and a 4GB JVM, running a single browser-based application under a Tomcat 7 service. It will run fine for a day or two, or sometimes a week or two, but eventually the CPU usage will creep up to 100% and then fluctuate between 95% and 100% until the application completely fails to respond. Our only recourse is to then recycle the Tomcat service. We have tweaked the "maxThreads" parameter but this has not resolved the issue. This only occurs on our production server under heavy use...we cannot duplicate this on our non-prod servers because we can't simulate that kind of load. We don't believe it is being caused by the application, but we don't know for sure. We're leaning towards some type of Tomcat configuration issue, but we just don't know where to go from here. Any ideas?  </p>
