3114	"mythbackend crashes with ""Unknown file transfer socket: 22"""	sean@…	Isaac Richards	"During LiveTV or watching recordings, the client machine will freeze, and then timeout with a message saying it cannot reach the server. The logs show that mythbackend crashing with the message ""Unknown file transfer socket: 22"". Sometimes the socket number is 15.

I have always had this problem, starting about 6 months ago with the server running on Gentoo, so I switched to Ubuntu to see if it was related to dependencies. Problem still occurred. Tried both Gentoo and Ubuntu on the client, and now Xebian on an xbox all with the same results. Just replaced the server with an entirely new box (3ghz) but same results. 

Used to happen maybe once a day, but now happens within an hour of playback.

Commercial detection and transcoding is turned off on the backend.

Ubuntu build appears to be 0.20.20060828-3
