Roamio crashing at/near end of playback

For about the last 2-3 weeks or so, my Roamio has been crashing frequently either at or very near the end of recorded programs, during playback.

I'll get either very near to the end of the show, or to the very end, and the box spontaneously restarts.

This is with reported software version b-tcdclient-quattro-3-12.2017.04.19-2200-USA-6-846.

Is anyone else seeing similar behavior?
