[mythtv] mythbackend leaking udp sockets

[Russell Mora]

Hi All,

Has anyone else noticed mythbackend (10296) leaking udp sockets?  E.g.

myth_master transcode # lsof -c mythbacke | grep UDP
mythbacke 5917 root    9u  IPv4              58918               UDP

myth_master transcode #

.... and the number just keeps going up and up - I've seen the backend
eventually run out of FDs (hits 1024 ulimit).  The weirdest part is that if
I strace the mythbackend process I don't see the socket calls - probably
just means strace is busted though.

I am willing to work on this but does anyone have any pointers?

Cheers,
Russell.
