Severity: 2-Critical

Symptoms

New standby device's tmm crashes and generates a core after high availability (HA) failover.

Impact

New standby device's tmm may crash. Traffic disrupted while tmm restarts.

Conditions

1. Enable inbound mode Endpoint Independent Filtering (EIF) in the source translation object. 2. Outbound traffic hits the source translation creating inbound entries. 3. Inbound traffic matches the inbound entry, and this connection stays alive. 4. high availability (HA) failover occurs. 5. Inbound connection closes, and the connection free comes from the BIG-IP system.

Workaround

None.

Fix Information

TMM no longer crashes with inbound traffic during high availability (HA) failover.
