[Bug 132774] [ipfw] IPFW with uid/gid/jail rules may lead to lockup

https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=132774

--- Comment #4 from Stefan Rink <stefanrink@yahoo.com> ---
Small update;
Not 100% sure if I'm hitting this one because it just freezes and I can't seem
to get into the debugger when it happens but I noticed it didn't freeze for a
week when I forgot to load IPFW on the machine and shortly after I loaded IPFW
and restarted a jail the node froze within a couple of hours. The console
usually complains about one of the bge interfaces of the lacp flapping when it
freezes.

This same hardware was running 13.1 without a single crash for more then a year
and there is still another node with the same hardware and configuration
running on 13.1.

Currently testing with IPFW but without any rules that contain jail ids and in
the meanwhile moving more stuff to the node in the hope it will crash faster.

Network config of the physical nodes;
[bge0 + bge4] -> lagg -> vlan -> jails while CBSD was the one creating count
rules that contain jail id's when IPFW was loaded. 

ps. We also have nodes running FreeBSD 13.2 without any issues but they have
different 'hardware' because they are virtual but do have IPFW and the 'count'
rules per jail.

- Created a new kernel with debugging and witness enabled but waiting until it
freezes again first.
