Thanks... I did it the hard way but I'll try to remember the easy way next time!

Gerry,

When you recieve errors with message queue, its likely t hat you have
gplt and device drivers that weren't shut down with gpend (either
interactively, or in one of your crons).

The command "cleanup -c" runs a script in $NAWIPS/bin/scripts to automate
the process, but you can accomplish  the same with finding the process IDs
of gplt, xw, gf etc using "/bin/ps -eaf" and killing those,
and then using the "ipcs" cammand to list open
message queues and remove them with the "ipcrm" command.

The cleanup script mentioned above tries to automate the process,
but since the /bin/ps output format varies so much between different
systems, you may have to do it manually as above.

No, That was the first, and obvious thought.  Declan and Daryl both came
up with a plausible starting point.  In looking at IPC resources, I had
problems.  A number of the processes were failing and leaving resources
hanging.

There was a reference Chiz had penned in 2000, recommending killing,
explicitly, running Gempak programs accessing gplt, based on an
examination using 'ps -efw' and then manually deleting the hanging IPC
message queues ('ipcs') using 'ipcrm' which cleared the issue.

I had attempted to duplicate a machine for gempak processing and had
failed to get some of the target/output subdirectories right. As the
scripts using those target directories couldn't write to 'em, the
scripts failed improperly, rather than gracefully.

So, rather than an easy-to-identify hard-disk error, it was a little,
but not much, more esoteric failure caused, as most of these things are,
by operator error.

Thanks for the suggestion, though.  Good thought.

Regards,
Gerry
