For some reason, eventloop is left with not removed connections which have been closed. I cannot repeat that situation manually refreshing page, but after/while testing application with ab or siege tool, I can see such connections in Resource array.
Probably due to improperly closed socket on client side, thous keepalive OS settings should be configured. In the meantime, server connections keepalive check could be implemented.
