i have newly purchased ccr-1072 . But i am facing huge problem if i put a single firewall then cpu become 17 to 25.

if i work on bandwidth management cpu becomes 50 %. If i disable any firewall cpu become 80 to 85.

Please help me on that

Post image from "Tools -> Profile" menu when this happens.

CCR 1072 cpu high if i put a single firewall or disable the firewall. please help me on that

The amount of traffic in your screenshots are significant, also as soon as you create rule in firewall it automatically enables connection tracking (very expensive firewall process) , if it is enabled, it will start tracking connections and will not stop until last one of them are timed out.

If i use more firewall or add 50 to 100 simple queue or manage bandwith then cpu becomes more high. But if do same thing in my ccr-1036 nothing happening . I mean it not increasing cpu if i disable or enable firewall. i have more than 1487 simple queue. it nothing happening with ccr 1036.

post your resources cpu status at moment of high cpu usage, like this

please be more clear. you are talking about 1036 and showing pics of 1009. No traffic going through interface/firewall rules is shown.

Brother its ccr 1009 its not my one. Its not about ccr 1009 or 1036.

Its about ccr 1072. In my ccr-1072 if i put minimal firewall or manage bandwidth with simple queues. then cpu became
high. I have already given pic for that. Please give me a solution.

impressive cpu use!!!!

whit this command you can see aggregate traffic, to know the total traffic passing through

Brother i am in big trouble . please somebody help me out.

can you plz check if any of the queue is being hit by dos attack or high pps. What is the rate of drop when traffic hits ur firewall rule. Queue wont be able to handle more than 1200kpps on 1072 to maxout the cpu. Correct me if I'm wrong

i agree

i think you are under dos attack

How could know that i am in dos attack? without queue and firewall its running fine . And If i use 1036 instead of 1072 its cpu 30 % only.

make a support file and send it to support. Please remember CCR wont be able to take heavy traffic on queues. There is already one post by me sometime last december showing it cannot handle heavy traffic(pps) on queues. Make a queue of around 500mb and send heavy udp 64b packet through that queue. Mikrotik ccr 1016 will maxout at just 300kpps.

Single queue, really?? FYI It is limited to single core, and other 71 cores probable are busy waiting on that one.
Use many sinple queues and you will be fine

We require mikrotik should involve to fix this problem. Its realy a big problem.

I have same problem 1036 30% cpu usage, same config in 1072 98% cpu usage

Dear All,
We are using CCR 1072 last couple of month, OS 6.38.7 BW handling apx 6 G Bandwidth. Usually its cpu usages 20-60% but last couple of days having strange type problem. suddenly its get cpu usages 100% and by this time traffic fall down. nobody get internet. and we cant log in to server to see anything. Its just hanged. After rebooted it is working fine like normal. We couldn't find any clue, If any body knows please give us solution. we are almost in trouble now. please give us feedback as soon as possible if anybody face that kind of problem and have solution.

Thanks in advance

Check Tool -> Profile menu to see what is using the CPU

Hi, I have a similar issue, its not constantly 100 but it spikes when a ppp interface like l2tp tunnel disconnects.

If there is 30+ dc's then 100% and this causes others to dc and worsens the problem

Did you check the Profile menu to see what is causing the CPU load?

Having the same problem here with a 1036
Cpu goes 100% unable to make suppout file.

The profile shows 100% cpu firewall usage. Disabled NAT/Contrack and now the 100% cpu usage is from a PCQ queue.
