We have 2x10G NICs configured in a bond interface and we are seeing randomly: RX errors 28751549  dropped 46541  overruns 28751549  frame 0We do have multiple VLANs running on this NIC so its a trunk port.The NIC is a Broadcom Corporation NetXtreme II BCM57810 10 Gigabit Ethernet (rev 10) I have the following RX ring buffer size.

It is happening on multiple servers, not in a single machine. We don't have that much traffic to fill the link also.
