Latest MLX Ironware 5.1: high cpu load issue?
I'm looking into upgrading my MLX8 boxes to the latest 5.1 release due to IPv6 VRRP-e support. I'm hearing there is an issue in 5.1 that causes significantly higher CPU load (30 to 40% where older SW only caused up to 10% on the same box/configuration) during regular operation.

I have not yet received details about this besides the comment the higher CPU load is being caused/seen in the IP_Rx process and might be related to some ARP issue.

Is anyone here using the latest 5.1 on the MLX? We're using NI-MLX-1Gx20-SFP and NI-MLX-10Gx2 on the boxes.

Haven't seen this on XMR. Using BGP, VRRP for both v4 and v6, no VRFs.
