[mythtv-users] Backend deadlock?

I've been having this problem for the past week or so where the
frontend stops responding when trying to play files. I've included the
frontend logs at the time of the error below, but there isn't anything
that might correspond with it in the backend logs.

The backend seems to stay online, but even after restarting mythtv on
the backend, the frontend still has these errors. The only thing that
seems to do anything is a complete reboot of the backend.

Any ideas what might be causing this all of a sudden? I am running
0.25.1 and have been keeping up with the -fixes from mythbuntu,.
