13.0-CURRENT drops to debugger on shutdown with IPNAT enabled

[David Boyd]

13.0-CURRENT drops to debugger on shutdown with IPNAT enabled.

Running in VirtualBox 6.0.2.

The identical configuration running 12.0-RELEASE-p2, 12.0-STABLE, 11.2-
RELEASE-p8 and 11.2-STABLE do not exhibit this behavior.

This (VM) is a test machine and I can do anything that will help
identify the root of this problem.

I have included screenshots of the debug output and a backtrace.


Thanks.

David Boyd.
