#10647: Scheduler deadlock during Live TV
--------------------------------------------+-------------------------
Reporter: stichnot | Owner: gigem
Type: Bug Report - Hang/Deadlock | Status: new
Priority: minor | Milestone: unknown
Component: MythTV - Scheduling | Version: Master Head
Severity: medium | Keywords:
Ticket locked: 0 |
--------------------------------------------+-------------------------
While watching live TV, got the popup indicating that the backend wanted
the tuner for a scheduled recording. I clicked "OK" to let the scheduled
program record. This resulted in an apparent deadlock in the scheduler
code. (To be precise, the scheduler wanted a different tuner but in the
same input group as the Live TV tuner.) The deadlock manifested itself as
mythfrontend and mythweb connection attempts hanging.
I attached gdb to the mythbackend process and got a stack trace.
Also including some backend logs with "-v most --loglevel debug". To make
the size manageable, I filtered out lines containing "TFW" or "JobQueue",
and I removed lines prior to 1 minute before the recording. (But I kept
the first 100 lines to show version and startup information.)
