| Description | LU missed number updates |
| Explanation | Stateful Failover assigns a sequence number for each record sent to the standby unit. When a received record sequence number is out of sequence with the last updated record, the information in between is assumed lost and this error message is sent. |
| User Action | Unless there are LAN interruptions, check the available memory on both Cisco ASA units to ensure that there is enough memory to process the stateful information. Use the show failover command to monitor the quality of stateful information updates. |
