Don't be. With httpd and Tomcat on the same box (or even the same LAN) the overhead of establishing the TCP connection on every request is minimal. Whilst theoretically there would be a performance issue in practice you won't notice it and it is much more stable. I have heard some reports of people seeing better overall performance.

Various causes, usually comes down to one end dropping the connection without the other one realising. HTTP keep-alive usually plays a part in this. Can also be related to connection time outs and when each end checks to see if the time out is expired. In short, disabling re-use removes all of these issues. > Do I still have a problem with my configuration? You could probably tune the time out and keep alive settings to reduce the issue but just disabling reuse is usually the better option.
