SG-5100 CPU usage consistently at 70 to 80%

klubar

Should I be concerned that my SG-5100 CPU usage is running consistently at between 70 and 80%? Nothing else looks too odd:

State table: 8%
MBUF: 4%
Temp: 38 degrees
Mem: 9%
Netgate SG-5100

There are about 5 openVPN users and the network load maxes out at 80 Mbs (in)/60 Mp/s (out). Average is much less.

Any way to find what is using the CPU? I'm a little concerned because I'd like to add a few more OpenVPN users and maybe kick up the internet connection from 500 mb/b to 1gb/s (which wouldn't increase the actual bandwidth used)

Diagnostics/System Activity will show processes.

Here is what I'm seeing:

What are the crypto settings set to?

Haven't seen that in a long while. Those rate processes should not be there.

Looks like they are running on different interfaces there. Do you have something monitoring bandwidth on each of those?

On Netgate's advice I rebooted the device and the CPU usage dropped back to less than 10% The only thing I can think of is that I leave the bandwidth monitor up all the time and that somehow created rogue processes. I guess I will not do that now.

I also updated the software to the latest version (2.4.5-RELEASE-p1) from 2.4.4p3 but I don't think that was the issue.

Thanks for everyone's help.
