There is not enough storage in the catalog address space currently available to process all the active service tasks. The maximum number of service tasks that might process simultaneously in the catalog address space has been lowered to ensure the availability of storage for task termination.
The system continues processing.
It is possible that contention exists for a system resource that is causing a backup of requests in the catalog address space. When this contention is resolved, the limit on the number of active catalog service tasks can be raised using the MODIFY CATALOG,TASKMAX command.
