The proxy gets a SUBSCRIBE request and attempts to send it to the status server but cannot open the TCP connection. This fails gracefully, but never notifies the UAC. The retransmitted UAC subscribes are ignored. The same behavior would probably occur for an INVITE forwarded to the registrar, though I have not been able to cause this condition.
This problem happens only when the system runs out of sockets. See xecs-1259 for more info. The increased number of sockets described in the comment by Lih-Shyng Tzeng - 2008-03-28 19:15 should greatly minimize any occurence of this condition. OTOH, the xecs-1259 fixes will allow this behavior to occur if we DO run out of sockets.
