Opened: Jan 06, 2023 Severity: 4-Minor
Unexpected failover or log messages similar to the following: sod[1234]: 010c0083:4: No failover status messages received for 1.100 seconds, from device bigip02(192.0.0.1) (unicast: -> 192.0.0.2)
A failover event could impact traffic flow.
- HA configuration network failover configured - DB variable 'failover.nettimeoutsec' set to a value of 1 second.
Following recommended practices of configuring network failover addresses using both the Management IP and Self IP addresses will reduce the chances of initiating a failover. Log messages may still be observed. Setting the DB variable 'failover.nettimeoutsec' to a value of 2 or greater should avoid the issue.
