Cause. An application either did not open or did not process $RECEIVE for all 
incoming system messages from the Messenger process.
Effect. The CPU appears to hang.
Recovery. Check the status of each process shown in the message. If you cannot 
make the process resume executing so that it begins to read $RECEIVE again (for 
example, by typing PAUSE on the home terminal), stop that process (this frees the 
pending messages from the Messenger process).
Correct the server process that was not reading $RECEIVE.
