When a high volume traffic is sent to a BIG-IP system, the Broadcom network switch driver might fail. The failure occurs because the switch driver is preempted (by tmm) from completing a long chip reprogramming routine and touching a watchdog. Sod, which monitors the watchdog, thinks the switch driver has become nonfunctional and kills it.
Potential eventual system outage if the Broadcom switch driver fails.
A very high volume traffic is sent to a BIG-IP system under certain circumstances.
A spurious Broadcom switch driver failure is not possible anymore.
