Hi,
I have a CCR-1072 with RouterOS 6.38.3, and use “hardware-queue-only” ininterfaces
Starting at 800Mb the networking process sometimes goes up to 30% -40%, and it stays for several minutes. Then returns to normal values without reason, even with the same bandwidth consumption.
I do not understand why it goes up so much. What reasons can make the networking process go up so much? What should I correct in my configuration to avoid it?
Thanks
Please,
some one can tell me, posible reasons for high cpu of “networking” proccess?
I can’t fix it 
I’m seeing a similar situation on a 1072 at 6.39.2. Did you ever figure this out?
I just save .backup file, put another 1072, load configuration… and cpu is better now
I think that this 1072 was wrong. Try save .backup and load it. If continue with high cpu, change sfp modules (I changed sfps and 1072 at same time)
And if you are using PCQ queues with more than 500Mb of traffic, change your queue tree and use another way of share bandwidth. When I removed PCQ, CPU ussage was lower
Don’t… now second CCR has same MAC addresses as first one. Next month someone (or you) decide to use it again, and bam… all sort of networking funkiness…
Use export command to transfer configuration between devices.

Lots… duplicated MACs, excessive broadcast, bad practices while setting up the router… see http://forum.mikrotik.com/t/pppoe-issue/110642/1
Tools > Torch may display useful information. A loop in the network can also cause high CPU as it floods the network.
Hi, are you using all 8 sfp+ interfaces?
And do you have something like a dhcp server setup on the device or using masquarade for the wan interfaces?
