Severity: 2-Critical

Symptoms

Under unlikely circumstances, tmm threads may run into synchronization issue at startup initialization, causing BIG-IP Failover

Impact

Impact is BIG-IP will failover at start time. If tmm has successfully started - no further impact will be observed.

Conditions

- SAML SSO or Form Based SSO are configured. - TMM is in process of starting (during reboot or for any other reason).

Workaround

Remove Form Based SSO, and SAML objects from configuration.

Fix Information

A thread synchronization issue that caused tmm startup issues has been fixed.
