Its been pretty busy around here.  Chiz is out of town at the moment,
so you will have to wait some more for responses to your GEMPAK-specific

Please send us the exact pqact.conf entry(ies) that you are using to
generate your CIMSS images.  I will start running them here and see if
I can reproduce your problem.  If I can, I will initiate a bugfix.

You could use the LDM scour to scour the CIMSS data directories.  Chiz
uses a variant of the script he wrote to prune NIDS directories.  The
only advantage in using his script approach is that it runs more
frequently than once-per-day (like scour typically does), so it keeps
the total number of images closer to the number specified in the script
invocation.  When you use scour, the number of files for any type of
image will grow throughout the day and then get lopped when scour
