I've rebooted the server (and hence restarted scoreboard and msgbserv)
and I still can't run anything from the scout environment - including
scored.  The nodes are reporting (or is it the server daemons doing the
reporting?) that their pm_ethernet devices are already open.

[root ＠ server score]# scout -g pcc
SCOUT: Spawning done.
SCOUT: session started.
[root ＠ server score]# scored
<1> SCore-D:WARNING PM ethernet/ethernet device already opened.

I'm the only user currently using the system so I know that nobdy else
is in a scout environment and is running jobs, but I've previous been in
a scout environment when the server wasn't configured correctly and
managed had a very unclean exit from an attempted job submission and
ever since the PM devices are being reported as in use.  What I'd like
to do is close these devices without a reboot so I can start scored.

Thanks,

John
