Have had mythbackend die a few times in the last week or so. Stubbornly
ignored it but now I just checked the log:

I have no idea what to make of it, but can see that at 23:39ish after all
those "bxxx000-bxxx0000" lines it crashes and restarts (have script to auto
restart it via cron check every minute).

Can the experts here translate that and what I need to do to prevent that
from happening again, if possible? To note, both tuners are recording and I
was watching a previously recorded program at the same time on my desktop
frontend.


Thanks very much
Bob
