[mythtv-users] Backend would not wake up on time.

[R Kannan]

Hello,

I have the backend (0.25 on Mythbuntu 12.04) set up to hibernate and
wake up 2 mins before any scheduled recording to record my shows. It
works most of the time but once in a while like last Thursday, it fails.
I went through the logs and found the following snippet...

Clearly before going into hibernate, it set the scheduled wake up time
to 1415933820.  'date -d @1415933820' gives...

Thu Nov 13 21:57:00 EST 2014

But the very next line in the log is on Nov 14.  So it did not wake up
or did not start the backend.

Is there anything else I can look into to investigate this issue further?

Thanks for any help
