Subject:dev.bce.X.com_no_buffers increasing and packet loss

Hi

I have a system that is experiencing mild to severe packet loss. The interfaces are configured as follows:

lagg0: bce0, bce1, bce2, bce3 lagproto lacp

lagg0 then is used as the hwdev for the vlan interfaces.

I have pf with a few queues for bandwidth management.

There isn't that much traffic on it (200-500Mbit/s).

I see only the following suspect for packet loss:

dev.bce.0.com_no_buffers: 140151466 dev.bce.1.com_no_buffers: 514723247 dev.bce.2.com_no_buffers: 10454050 dev.bce.3.com_no_buffers: 369371

Most of the time, these numbers are static, but every once in a while they increase massively by several thousand, but only on 2 interfaces. The 1 minute average rate on those interfaces is 266/s and 123/s.

Does anyone think this is related to the packet loss or are these counters just a red herring? Is there anything that can be done to reduce this count?

Ian
