That's a state of the TCP connection:

I _think_ that the conn_max_pending and conn_max_pending_auth help
control this.
Also, you can use the idletimeout directive to control the
disoconnections of unused/stale connections.
The docs also discuss the keepalive directive, but I've never used
that.

IIRC, From lsof, you can learn PIDs and file descriptors. You can access
the FD through procfs.
