I sup'd last night (4/24/94), and rebuilt my kernel (I had previously
successfully crossed the river off_t ;-). It booted fine and appeared
to work great. I then set things up to rebuilt everything - cleandir
+ all + install.
This ran all night, and this morning I found it churning on
/usr/libexec/makewhatis /usr/share/man
(which is odd, since looking around later makes me thing it got a lot
farther than that, but...)
I opened up another remote X window, fooled around, and the did "ps -axl".
Suddently everything stopped - I looked at the console and found a panic
in vfork. I believe this was the csh forking ps.
kernel: protection fault trap, code=0

I have not looked at this real hard (I will), but I figured I'd report it.
