Can you take them down by hand? just which files/lines it finds the
inconsistency? Yes, it is pretty serious.

| I've installed a GENERIC kernel with `options LOCKDEBUG' added. The 
| backtraces are much more verbose. But I can't grab them. They don't end 
| up in the dmesg output and I get nothing from savecore.
| 
| Is there another way to get at those messages? Perhaps in single user 
| before swap is configured?
| 
| What i did from ddb is...
| 
| t /l
| continue
| 
| ... it sync'd disks then rebooted.
| 
| This seems to be a serious problem, should I be filing a PR once I get a 
| reasonable backtrace?
| 
| BTW - It looks like this is definitely happening with ftp processes 
| only. IPFilter (ipnat) has its basic ftp proxy rules installed, i.e...
| 
| map ae0 192.168.1.0/24 -> 0/32 proxy port ftp ftp/tcp
| 
| ... I don't know if that could be something, but there it is.
| 
| Thanks for helping,
