Traffic-groups become active/active for 30 seconds after a long uptime interval. Note: Uptime required to encounter this issue is dependent on the number of traffic groups: the more traffic groups, the shorter the uptime. For example: -- For 4 traffic groups, the interval is ~1242 days. -- For 7 traffic groups, the interval is ~710 days. -- For 15 traffic groups, the interval is ~331 days.
Outage due to traffic-group members being active on both systems at the same time.
-- Two or more BIG-IP systems defined in a device group for sync/failover. -- There is one or more traffic groups configured. -- The BIG-IP systems have a long uptime.
There is no workaround. The only option is to reboot all the BIG-IP units in the device group on a regular interval. The interval is directly dependent on the number of traffic groups.
Traffic groups no longer becomes active on more than one BIG-IP system in a device group after a long uptime interval.
