The system data mover has previously detected a fatal error condition that prevents further processing and is now terminating its address space.
The system data mover issues a cancel system command to terminate its address space.
If a command was being processed for the session at the time of cancel, the control address space will not process another command for the session for up to 10 minutes.
Look for preceding messages that identify the fatal error, correct the condition, and restart the XRC session.
If subsequent commands issued to the session appear to hang, recycle the control address space by issuing the command CANCEL ANTAS000.
