I finally figured out what was causing the massive disconnections of servers on the backend. A fix for this will be uploaded today/tonight at the latest.
Basically, for flow control reasons... I track the number of bytes sent and the number of bytes acked, if the gap between these 2 values gets large enough I hold off sending any more data until it's acknowledged. Due to a bug in the acknowledgment code, it would have removed an ACK packet instead of a DATA packet, causing a slow leak everytime the sequence numbers were reset.
Additionally, as the numbers leaked, it would make communications between the servers slower and slower over time, until eventually it couldn't send anymore data because not enough bytes have been acked causing a timeout and a disconnection.

FYI... my fix didn't work, so I rewrote the throttle code for the socket which was causing the problem. Update later today or tonight and then it really should be fixed this time.

This sounds like the trouble I was having. I wonder if I helped fix it by sending in my tracelog file?
