CFDTLRSW

If you have a task waiting on resource type CFDTLRSW, the task is waiting for a free locking request slot to become available. CICS places a limit on the number of locking requests (that is, requests that might acquire record locks) that a region can have simultaneously running in a coupling facility data table server. This limit is known as the locking request slot (LRS) limit, and it avoids tasks that hold locks from preventing other coupling facility data table accesses. If the number of locking requests currently running in the server for a CICS region has reached the LRS limit, this request waits for one of the locking requests to complete.

Waiting on this resource can occur only for files defined to access a coupling facility data table, and only for record access requests that could potentially require a lock.
