COF531I DLF INTERNAL TASK taskname HAS ENDED mm OF A MAXIMUM nn TIMES.
Explanation
During data lookaside facility (DLF) processing, an internal task that normally operates continuously has ended the number of times indicated. The task will not be reattached once it has ended the number of times listed as the maximum.
- taskname
- The name of the task that has ended a number of times.
- mm
- The number of times the task has ended.
- nn
- The maximum number of times the task can end before being detached.
System action
The system continues DLF processing. At a point before the maximum is reached, DLF will issue messages recommending that DLF be shutdown when convenient. Once the task ends and is not reattached, DLF will not be fully functional.
If mm and nn are equal, and the taskname is COFMDORT, DLF will no longer be able to enqueue on retained DLF objects, so the DISPLAY DLF,RES=(SYSZSDO,*) command can no longer be entered to determine what DLF objects are retained.
Operator response
Notify the system programmer.
System programmer response
