Nice catch. I think I see the bug. It's tearing down the global nfs4_file_rhltable in the per-net shutdown procedures, which leads to a double free after a containerized nfs server is shut down. You can probably reproduce this by starting the NFS server on the host, and then starting another one inside a container. Then shut the containerized one down and then the one on the host. Presumably, that should make the machine crash with a similar stack trace.

Good to know, now I can reproduce it 100% according to your tips :) thanks Jeff! *** Bug 2170140 has been marked as a duplicate of this bug. *** Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA.
