I suspect that it's a GEMPAK issue.  I think that one or more of the GEMPAK 
decoder processes is continuing to run despite its parent pqact(1) process 
terminating and closing the decoder's input stream.

You can verify this by kill(1)ing the remaining GEMPAK decoder processes.  This 
should cause the ldmadmin(1) script to terminate.

Please let me know what you discover.
