A queue having a "duplicate' counter associated with each entry whereby duplicate data is not stored in the queue. Before data is placed in the queue, the queue is searched for an entry matching the data to be written. If a match is found, the duplicate counter associated with the entry is incremented. Further, if a match is found and the data stored therein is inconsistent with the current data, the contents of the queue are updated and the duplicate counter associated with the entry is reset to one. If a match is not found, the data is written to the queue and the duplicate counter associated with the entry is initialized to one.
