Error description
This error occurs when another job already has the Interval dataset (CQMINTER) opened when CQM is trying to open it. The open failure subsequently results in an S138 ABEND indicating CQM is issuing an ENQ for a resource it had already ENQ'ed on. In the normal course of processing in every interval, CQM opens and updates the INTERVAL dataset. Before opening the INTERVAL dataset, CQM issues an ENQ, once done with the INTERVAL dataset, it closes it and issues a DEQ. In this case the open failure causes CQM to bypass the DEQ, resulting in all subsequent intervals to fail on the ENQ because it is already held. From that point CQM stops collecting data because the INTERVAL dataset is not available for its processing.
