[mythtv] Backend not releasesing deleted files.

[Brent Borghese]

I think you are seeing the same problem I have.   I think the cvs did
help the problem a little, but the problem is still there.

I have been looking in to it and here is what I think the backend is
doing:

I run one backend and have 3 frontends(1 one the backend computer, 2 on
other computers), if one of the frontends crashes or I turn it off(Yes I
crash my frontends every day, ext3 is great) while it is playing a show
the backend never closes the TCP/IP socket, so the backend keeps the
.nuv files open forever.

Here is why I think this:
Right now I have the backend and just the local frontend running.   But,
my backend server is showing the backend task has 9 IP connections.   

mythbacke 30644 mythtv   20u  IPv4     191646                   TCP

mythbacke 30644 mythtv   39u  IPv4     255860                   TCP

mythbacke 30644 mythtv   49u  IPv4     312234                   TCP

mythtv.inside:6543->mythtv2.inside:32887 (ESTABLISHED)

mythtv.inside is the backend server (2 connections)
mythtv1.inside is a remote frontend (1 connections, computer is off)
mythtv2.inside is a remote frontend (6 connections, computer is off)

And the backend has 7 open nuv files, it should have 2(it is currently
recording 2 shows)

To check your backend do:
lsof|grep IPv4|grep mythback|grep ESTA
