So remove it and don't put it back. > 2. But I had the same property in tomcat 6 and it worked fine on that. Clearly something is broken with your app / Tomcat 7 configuration. Using maxThreads=5000 when you are only servicing 9000 requests in 1800 seconds with an average processing time of less than 1s per request is not only excessive it will mask any connection related problems you do have. The default of 200 should be fine. Since you are using APR, you don't need a thread to maintain a keep-alive connection so I would reduce maxThreads to no more than 20 for now to aid debugging. Once you have fixed the problem, then you can restore the default. > A.

That is pretty much completely unhelpful. a) you need to tell us what you are changing and what the results were and b) you should only change one thing at a time. > *Point 4* > 4.

Connections != requests. Please make sure you use the correct terminology because if you don't it will cause confusion. Point was was related to old, invalid attributes you had in server.xml that should be removed. > A.
