If the creator of the note pad requires XCF to perform lifetime tracking of the maximum note tag value, the note pad might contain notes that are pending delete. See Note pad protocols for more information. When the note pad appears to be full or constrained, XCF initiates processing to physically delete the notes in a pending delete state and resends your note operation to the coupling facility (possibly more than once). Thus the existence of notes in a pending delete state will not generally be a contributing factor when XCF rejects a request because the note pad is full or constrained.
