system gets into state where bridges collapse within a few seconds

calls kept flowing into the system, but bridges would collapse without error within a few seconds of starting.

Seems to be happening about once a week.

This particular system has only ever run 16.10

I have a core dump from the running system and full logs including a period with debug set to 4

below is a typical call flow while the system was in this state.
