CCTL thread looping

Use CCTL commands to determine if the CCTL is looping or if it has issued a DBCTL request and is waiting for a response. Refer to your CCTL documentation if the CCTL is looping. Otherwise, issue the /DISPLAY command to find the region with the recovery token that corresponds to the CCTL task that is waiting for a response from DBCTL. Then use the /STOP REGION command to force that thread to end.
