#9733 closed Bug Report - Hang/Deadlock (Fixed)

Putting FE to S3 sleep deadlocks BE

Description

My sys is 3x ION FE on minimyth derivate + separate BE. 0.24-fixes git20110416 on ArchLinux?. I'm using S3 suspend for my disk-less FEs.

I have issues with BE deadlock when any of FE is put to S3 sleep.

Use case:
2 FE
-FE1, FE2 are running
-Sent FE1 to S3 sleep, keep FE2 idle
-After some time (15-30 min) try start LiveTV on FE2.
-FE2 behaves like with deadlocked BE (famous "cant determine MYTH_PROTO_VERSION...." in logs)
-Resume FE1
-FE2 LiveTV now works again as expected

Above scenario is repeatable.
BE, FE logs attached. Also gdb backtrace from deadlocked BE is attached. br
