Symptom: A maxaged LSA (with age much bigger than 3600) might be present in the ospfv3 database, and on the maxage list. The reason for not deleting the LSA (which can be displayed with "show ospfv3 database <LSA_type> <LSA_ID> internal" is "Ack count not zero" Conditions: The problem may happen under special timing conditions, when the interface goes down in ospfv3 while the process was waiting for an ACK for that LSA from the interface.
