When load balancing HTTP requests, the BIG-IP system matches client-side and server-side connections. When connections are shutting down, a race condition may occur on a busy system and peer connection reference can be lost.
TMM crashes causing failover. Traffic disrupted while tmm restarts.
-- The BIG-IP system has a standard virtual with HTTP profile and HTTP router. -- The BIG-IP system has high CPU utilization.
None.
The race condition has been corrected, so TMM no longer crashes in a busy environment when handling HTTP responses.
