Message: %ASA-3-210003: Unknown LU Object number.

Event 210003 is generated when Stateful Failover receives an unsupported logical update object and is unable to process it. This might have been caused by a corrupted memory, LAN transmissions or other such events.

How could you resolve this situation?

If this even keeps recurring, check the Stateful Failover link LAN connection. If the error had not caused by a faulty failover link LAN connection, determine if an external user is trying to compromise the protected network. Also, check for misconfigured clients.
