TMM may crash with a very high number of concurrent connections (e.g., 30 million).
Traffic disrupted while tmm restarts.
This happens if BIG-IP has a lot of concurrent connections and encounters HSB ring drops. At that time if ICMP monitors are configured, then LTM will QoS promote those ICMP monitor flows and if those are for the same endpoints, then tmm might crash.
TMM no longer crashes with a very high number of concurrent TCP connections.
