[McIDAS #AOE-843254]: problem with DEV=T

Hi Owen,

Well, I have been poking around on gale for quite awhile now.  I can
easily/repeatedly cause the DEV=T error you reported, but I see no
apparent reason for it in McIDAS.  Also, I replicated your setup on
my workstation here at Unidata; I can _NOT_ reproduce the problem
on my machine!

The fact that things seem to run without problem on my machine
got me looking at the shared memory on gale.  I see that there
are several shared memory segments that are waiting to be deleted
(where the status is listed as 'dest'):

gale:[114]% ipcs

------ Message Queues --------

This hints that there is a problem releasing shared memory, and that
is seemingly calling for a reboot of the machine.

Please call if you want to chat about this (303.497.8642).

Cheers,

Tom
