[Kamailio-Users] TCP ZeroWindow and TCP Window Full

[Gawith]

There's not that much traffic. Perhaps 200 TCP packets per second.
Kamailio starts with the ZeroWindow.

I also see single "core:handle_io: empty fd map" in the logs and after 
that Kamailio sends a TCP RST packet.

I have no clue how to debug this.
