A hitless failover has occurred and any IP multicast database entries which were deleted after the failover were saved so that re-learned entries can use the same IP multicast table entry for faster convergence. This message indicates that after waiting some time the specified entry was released from this temporary database since it was freed since the failover but not yet relearned.
This is an informational debug message so there is no remedy.
