in your attachment, "Http Used:2484", "Requests In Processing:2155". this is high.

but no info about external App? in Real-Time Stats page, click "Show" button beside "External Application" can get the info.

Does the server serve a lot of static content? Maybe you should try the 4.1RC release with AIO option enabled.
