Intermittent tmm core under load.
The BIG-IP system stops processing traffic while the TMM restarts.
-- Provision APM (at least). -- Additional required conditions are not well understood. -- Seems more likely to occur when APM is provisioned with other modules, especially ASM or AVR.
Tmm core no longer occurs with high APM traffic.
