We had a customer who did the same thing. The system would hang if too many people would log on using the same id. Make sure they use different ids. Otherwise it seems that internal system tables are getting filled up. Also, how much memory is in the system? We figure that the base system needs about 1 meg, and then we add 512k for each additional terminal. It seems to work. As I understand RM/Cobol is a memory hog.
