MikroTik

Good afternoon,

I have several load balancers with Mikrotik RB750 and 750G, some with versions 4.16 and others with the newest 4.17.

The problem is that sometimes and appears to be randomly the CPU goes 100% for several hours or days.

Here are some images.







I am using PCC and in some cases NTH.

Here is the configuration of mangle.

Thanks in advance.

Try upgrading to Ros 5.4, and use profiler to see tha CPU consuption...
