[yocto] Strange bitbake error

[Gary Thomas]

For the last couple of days, I've been seeing my bitbake builds
just shutdown, without actually completing, like this:

Initialising tasks: 100% |###################################################################| Time: 0:00:10
NOTE: Executing SetScene Tasks
NOTE: Executing RunQueue Tasks
ERROR: Worker process (22132) exited unexpectedly (-9), shutting down...
ERROR: Worker process (22132) exited unexpectedly (-9), shutting down...
ERROR: Worker process (22132) exited unexpectedly (-9), shutting down...
ERROR: Worker process (22132) exited unexpectedly (-9), shutting down...
WARNING: /local/poky-cutting-edge/bitbake/lib/bb/runqueue.py:1159: ResourceWarning: unclosed file <_io.BufferedWriter 
name=31>
   self.worker = {}

This happened after completing ~650 out of 5786 tasks.

If I rerun the build it will likely complete without any more errors.

Any clues what might be happening?  Is there any information (logs, etc)
that might help me understand?

BTW I'm using the latest Poky (62d7d4130202d8ede16abf9e7d779361ca70847e)
updated just a few hours ago.
