Looks like an overloaded server to me. It is strange that there are so
many processes in 'R' state. This looks to me as some clients are playing
games with your server by connecting it but not sending a request.

It is only written once during the livetime of the server. So in your case
above: As it appeared immediately after the start of the server it will
never appear again until you restart the server.
