Hi,

Question on killing processes which are hung, but have resources locked (this
on 2.0.5R):

I was doing a dump to my floppy tape when it aborted with an "unexpected 
interrupt" message.  I flipped over to one of the alternative consoles and
tried to kill the dump.  The ft process wouldn't die.  And I couldn't rerun
the command because ft had /dev/rft0 locked up.  Had to reboot the machine
to recover.  Now this isn't a problem on my home machine, but I'd like to
bring up some production machines at work with FreeBSD.  My question is how
to kill processes like this without a reboot?

TIA,
Bud Dodson
