>Description:
I have a LFS /usr/obj.
After some days, I usually get:

Nov 14 00:36:51 hiro lfs_cleanerd[137]: bad segusage count: -5120

This keeps repeating every second.
When I use the LFS file system some more, I usually get a kernel panic.
Using X, I don't see the panics, but I can try to get one if necessary.
>How-To-Repeat:
Use LFS on a machine that has a daily reboot cycle, and on which said LFS
is used as /usr/obj for pkgsrc quite often.
Another machine that stays up most of the time does not show these symptoms.
>Fix:
Sorry, no clue.
