But you have overridden the default with a class that does not exist in Tomcat. I'm not sure what Tomcat will do if the class is invalid. Or maybe your developers have patched Tomcat to include a new SSLImplementation class? That would make sense if (a) you have an odd-looking sslImplementationName configuration setting and (b) your I/O channels are behaving strangely (because you have a broken I/O implementation). > 2.

Are you indeed using a load-balancer? If you are, then having a long keep-alive timeout is actually a *good* thing, because it will improve performance between the lb and Tomcat. But no individual real-world client needs a 5-minute keep-alive timeout. >> I think the threads are based on the number of requests is it >> true? It's complicated. Usually, your thread pool will contain the number of threads equal to the high-water-mark of the number of simultaneous request (plus or minus a few, depending on timing). If it's not configured correctly, those threads will never be released. Whether or not that's a Bad Thing in your environment is up to you. > 3.
