I set this even lower (to 120s) because it's said it's the timeout for reading of each packet and no application on the Tomcat should take so much time to send any part of an answers. I might be of worth if you pass the URIs of the dangling requests to developers. Because not finished, they are not logged. But you may take a look on the scoreboards of the Apache or the Tomcat. On Tomcat, it available via an MBean, you may read out it via JMX or via the http-proxy of the Tomcat Manager application. I may send you a script as a pointer, if you like. Guido
