KDFAP1550S SERVICE REQUESTS DISABLED DUE TO CHECKPOINT FAILURE

Explanation
 			 				This message is issued after a fatal checkpoint failure 				has been detected. Refer to messages issued prior to 				this message to determine the exact cause of the 				failure. 			 		
System action
 			 				The service request being processed fails and an error 				return code is set for the request. Additionally, 				service request processing is disabled and no new 				service requests are accepted. 			 		
User response
 			 				Ensure that the OMEGAMON® II checkpoint data set has not 				been overwritten and free space has not been exhausted. 				If the checkpoint data set is damaged, the data set can 				be restored to its original state from a data set backup 				of the VSAM cluster, or it can be deleted and recreated. 				Restoration can cause the loss of service requests that 				were checkpointed after the backup was taken. This 				problem can occur because a large number of service 				requests were issued and never deleted. If a large 				number of unwanted service requests are retained in the 				checkpoint data set, issue delete requests to allow 				storage in the checkpoint data set to be reused.
