Comment (by Robert Verspuy <robert@…>):

 Just updated git to latest version master [v0.25pre-4071-g664a880]
 I started the BE, everything ok, then connected with a FE, all still ok.
 Then I started a recording. Everything still ok. Then I manually stopped
 the recording.

 The recording keeps running in the background. And the FE gives back the
 following error:

 2012-01-16 10:12:37.708916 I  Connected to database 'mythconverg' at host:
 2012-01-16 10:13:51.980575 E  MythSocket(7f0408013d30:51): readStringList:
 Error, timed out after 30000 ms.
 2012-01-16 10:13:51.980669 N  Connection to backend server lost

 I ran gcore to create a core file from the BE, and ran a "thread apply all
 bt full"
 output is attached ( backend_deadlock_backtrace.txt )
 I think it has the about the same output as the last attached backtrace,
 but that trace ended with a "not enough registers or memory" line, so I
 don't know if that trace is complete.

 This situation also happens when a scheduled recording stops.
