Hello,

One from a lot of RB450G runing with 100% of cpu utilisation.
Is it hardware of software problem? How to disable health problem or

Not sure about the health problem, but high management cpu usage is usually caused by snmp … try disabling snmp.

JanezFord,

there is no difference between different SNMP settings.

I don’t know what in health would be using up 71% of the CPU.

Best answer probably come from a supout file (either looking at it yourself in the viewer or sending it to mikrotik) and get some real answers.

I have exactly the same issues after upgrading from 5.14 to v5.26 on RB450G.

CPU usage today suddenly locked up at 100% without apparent reason. I had to reboot the device to get it working again.
