     I presume that the server is a Linux box?  If you can get root on the
box that houses the server, try changing _its_ keepalive timeout to 300
seconds.  That might do it for you.

     The serverloop itself is a bit more complex conceptually than the
clientloop and already implements a timeout in order to collate small
transmissions into larger ones.  The attached patch should be categorized
under "Garish Malformed Hackish Patchlets" and is not really implemented
right but could give a general idea of where you'd have to work to
implement ignore packets in the serverloop.
