## Symptoms

- Sudden failover and recovery of the Standby VS in a VSX cluster with three or more members.

## Cause

Flow of events:  

1. A sudden issue such as interface flapping causes the Standby member to switch to Down status.
2. The Backup members switches to Standby, holds and synchronizes the connection tables with the Active member.
3. The Standby member issue is resolved, therefore the connection goes back to Standby.
4. The Backup member still holds the connection table but it is not synced with the Active member.
5. In the Backup member, the TTL of all connections continuous to decline until it reaches 0, then it terminates the connections from the connection table of all the cluster members.
