#13062: Backend does not schedule new recordings unless restarted

--------------------------------------+---------------------
For several months now (I'm not sure exactly how long) my combined FE/BE
system does not schedule new shows to be recorded unless the backend is
restarted.

Both the reschedule attempt from running mythfilldatabase and manually
running mythutil --resched have no effect.

The restart (via systemctl) takes much longer than it used to as well.

System is Fedora 25 x86_64 and I am the current package maintainer for RPM
Fusion.

Comment (by pbennett):

I recommend running mythutil --resched at a time when it is not working,
and capture the backend log at that time to see whether there is any error
and whether it performed the reschedule. Please post that part of the log
here.

Comment (by pbennett):

It seems to not be doing the reschedule. Here is my backend log for the
same operation. It includes lines confirming the reschedule and showing
the result of the reschedule. Something is preventing the reschedule in
your backend.

Comment (by Richard Shaw <hobbes1069@…>):

I'm only about 12 commits behind current fixes/0.28 and nothing from the
log appears to address this so I'm at a loss on where to look.

Comment (by gigem):

You'll need to enable more backend logging. Add -v schedule at a minimum
and possibly --loglevel debug. The scheduler is likely getting stuck.
Several deadlock scenarios were fixed long ago, but perhaps there's
another one. If that's the case, you'll probably need to use gdb and get
a stack trace to see where it's stuck.

Interesting, mythutil --resched seemed to work right after restarting the
backend... I'll have to give it a few days and try again.

Just tried mythutil --resched after adding -v schedule and --loglevel
debug and no new information.

Changing to -v all and restarting.

Ok, this is with everything turned on so I guess it's full debugging next
unless you see something useful.

Unfortunately, those logs don't help. You will need to get a backtrace
using gdb so we can try to see where things are stuck.

Comment (by Richard Shaw <hobbes1069@…>):

Any hints on the procedure? I've figured out how to attach to the running
process and can install the debuginfo packages. Since it pauses the
process once I attach to it, do I just use "next" and "bt" until I find
something interesting?

Comment (by Richard Shaw <hobbes1069@…>):

Ok, trying... I installed the mythtv-debuginfo package, attached to it,
did a continue, a mythutil --resched and "thread apply be full whatever"
and it never came back to a prompt after more than an hour. Now I've
installed 4.2GB of debuginfo packages for all the dependencies and have
waited 20 minutes to get a prompt after entering "continue" and
mythbackend is stuck at 100% cpu...

Comment (by Richard Shaw <hobbes1069@…>):

Another data point, although not particularly helpful. It wasn't GDB that
was causing 100% cpu usage. Apparently whatever the issue is, is causing
the problem. Restarting mythbackend and CPU uses drops to near 0% while
idle.

I wonder if I can use something like vmstat to track it over time and see
when it starts consuming 100% cpu...

Comment (by gigem):

You can tone the logging back down since it wasn't helpful. I doubt
vmstat will help, but it shouldn't hurt either. Once you are at the gdb
prompt, the backtrace shouldn't take very long at all.

Comment:

I finally got around to reviewing your gdb log. Unfortunately, it doesn't
appear to include mythtv debugging information, so I can't tell where it's
stuck. Do you compile mythtv yourself or use packages? If the former,
you'll need to recomple with compile-type set to either debug or profile.
If the latter, you'll need to look for a "debug" package version or
compile mythtv yourself.

I actually make the RPM Fusion packages and the debuginfo packages were
installed. I'm not sure why it didn't work...

Comment (by gigem):

Okay. Did you attach gdb to an already running mythbackend? If so, maybe
you need to be in the mythtv source directory, or tell gdb where to find
the source, in order for it to include the line numbers when in the mythtv
code.

Comment (by gigem):

What is the exact MythTV version you are using? The line numbers don't
match up with the latest fixes-0.28.

Anyway, it doesn't appear to be the traditional Scheduler deadlock. This
appears to be a deadlock in one of the recorders.
