rcv_fifo_overrun on all ethernet interfaces

Hi All,

I want to ask if you encountered the same issue after updating the firewall software to 10.1.6-h6, we started seeing these errors.

Does anyone know which version could fix it?

@Metgatz

Thanks for your feedback, I have investigated that as well. However, the ports are nowhere near 50% utilization during peak hours, 4 ethernet ports are load balanced and all of them exhibit the same behavior which generates rcv_fifo_overrun.

Prior to updating the firmware, our monitoring logs are clear. After the update the following day, it started to generate that error.
