Thanks for your replies to my problem spawning.  Using SDA to examine 
the problematic process on the running system was very helpful in pinpointing 
where and how channels were left assigned in the program.  It turned out
that a program called FILE_ORG which we got off the network last summer 
was the culprit, so I replaced it and all works fine now.  Thanks again.
