Hi,
I've got a problem on a 4.7-RELEASE machine. I tried using
/usr/bin/truss on a process (which was running in a chroot
environment, which in turn is on an NFS-mounted filesystem,
if that matters). But now I cannot kill the truss process
itself anymore, it's hanging there for a few days already.
:-(

Accoding to ps, the truss process is in "disk wait" ("D"),
but all disks are working perfectly fine, including the
NFS-mounted filesystems.
The process that had been trussed ("jws") doesn't run any-
more (I had to kill it, using SIGKILL, I think).
Does anyone happen to have an idea how to get rid of the
truss process? I cannot reboot this machine.
Regards
Oliver
