Ticket #10955: another backend deadlock

#10955: another backend deadlock
------------------------+--------------------------------------------
Reporter: brian@… | Type: Bug Report - Hang/Deadlock
Status: new | Priority: minor
Milestone: unknown | Component: MythTV - General
Version: 0.25-fixes | Severity: medium
Keywords: | Ticket locked: 0
------------------------+--------------------------------------------
BE failed to record the scheduled programming this evening. Not even a
peep about it in the logs. Mythweb's Status page was failing to load
which I have found to be a good indicator of deadlocked backend threads.

Currently I am only one commit from the tip of 0.25-fixes:

{{{
MythTV Version : v0.25.2-8-g3256849
MythTV Branch : fixes/0.25
Network Protocol : 72
Library API : 0.25.20120506-1
QT Version : 4.8.1
Options compiled in:
linux profile use_hidesyms using_alsa using_oss using_pulse
using_pulseoutput using_backend using_bindings_perl using_bindings_python
using_bindings_php using_crystalhd using_dvb using_firewire using_frontend
using_hdhomerun using_ceton using_hdpvr using_iptv using_ivtv
using_joystick_menu using_libcec using_libcrypto using_libdns_sd
using_libxml2 using_lirc using_mheg using_opengl_video using_qtwebkit
using_qtscript using_qtdbus using_v4l2 using_x11 using_xrandr using_xv
using_bindings_perl using_bindings_python using_bindings_php
using_mythtranscode using_opengl using_vaapi using_vdpau
using_ffmpeg_threads using_live using_mheg using_libass using_libxml2
}}}

Other anomalies I have noticed since upgrading to this version is that
when I am done watching something and delete it, a few minutes later a
dialog will pop-up in the UI of the FE telling it could not delete the
recording since the file it's in was missing.

I will attach the threaded stack trace per usual.

Comment (by brian@…):

My apologies for compressing the stack trace if you typically don't like
it compressed. Your Trac system has a limit on the size of attachments
and this stack trace exceeded that.

Comment:

This looks like a dup of #10870. That issue has only been patched in
master so far.
