[mythtv-users] Fwd: Intermittent MultiRec Failure on HD-5500 After Upgrade to 0.25-2

[Junk Moody]

I've now experienced this problem on my HD550 with one 1 program recording
(with MultiRec=3).  Tuning failed.  Bouncing the backend restored the
recording capability.  Up till now I only saw the problem with 2
simultaneous (multiplex) recordings on the same tuner.

The mythbackend.log at the time of the failure (15:30:00) is below.  The
failed recording is ""College Football":"Temple at Penn State": channel
2071 on cardid 11, sourceid 2".  The recording on the other HD5500 worked
correctly.

Subject: Intermittent MultiRec Failure on HD-5500 After Upgrade to 0.25-2
To: mythtv-users at mythtv.org


I've recently upgraded from MythTV 0.24 to 0.25-2 and I now get
intermittent recording failures which prevent all future recordings until
reboot. I've deleted all tuners and re-added them after the upgrade with no
change.

Several dozen MultiRec recordings will happen just fine, and then a
recording gets "stuck" on a tuner and all future recordings on any tuner
seem to not get dispatched. Several hours after the recording should have
ended the "stuck" recording is still shown as green in Previous Recordings
list along with status O, implying it is still recording, but no file is
created; missed recordings don't show in the Previous Recordings list at
all. After reboot the missed recordings show as red with status M in the
Previous Recordings list.

So far all failures have occurred only on HD-5500 (2 different systems) and
only when MultiRec>=2. HDHomeRun with default MultiRec=2 so far has not
shown the problem. Also HD-5500 with MultiRec=1 (no MuntiRec) has not shown
the problem.

I can't see anything in the mythbackend.log to help identify a problem.
Suggestions?
