In some rare circumstances, the High-Speed Bridge (HSB) device might fall or drop off of PCI bus, resulting in the BIG-IP system not being able to process traffic. If this happens, a daemon_heartbeat failsafe gets triggered instead of dataplane_inoperable_t action.
The BIG-IP system unable to pass traffic and a failover is triggered.
The conditions that lead to HSB to fall off of PCI bus are unknown at this time.
Reboot the device or the blade to recover from the situation and monitor for re-occurrence. If it happens again, it could indicate potential underlying hardware issue.
