Symptoms

When a BIG-IP device has been running for 8 weeks or longer without a restart of TMM or a system reboot, BIG-IP services can be disrupted.

Impact

Traffic disrupted while TMM restarts.

Conditions

-- BIG-IP device has been running for 8 weeks or longer without a TMM restart or system reboot. -- The BIG-IP system's internal risk-policy subsystem (used by the security features) has not been configured to communicate with an external risk-policy server. -- In a vCMP configuration, the BIG-IP 'host' instance is susceptible, since no security features can be configured in its context. -- A BIG-IQ device running any BIG-IQ v8.x release prior to 8.1.0.1 is also susceptible.

Workaround

None.
