High CPU Usage on my CRS125-24g-1s

RouterOS Beginner Basics
1

I am getting a average cpu usage of about 9% to 11% on my CRS125-24g-1s.,

Issue is that is not doing anything? I have one lan cable plugged into to to access winbox.

Im in the process of configuring it and I just noticed the high cpu usage.

Where can I start looking to find out the cause of it?

What routeros and firmware on your routerboard?
Upgrade to the latest routeros 6.12 and update bios

maybe it’s similar to rb2011 ..disable LCD and see if cpu go down

I have been on 6.12 since I got it.

I can try disable the LCD.

I did notice the other day, all the Ethernet ports are one switch 1.

But when I look under switch settings it names it as this (switch 1 - cpu)
hasnt the crs got dedicated switch chips?

I disabled the LCD and BAM

its back to 5% / 6% with traffic :smiley:

I guess there is an oopsie with the lcd?

Enabling and disabling the LCD definitely makes a difference. However the LCD isn’t even on, its sleeping.
I dont see why it needs to use any CPU while sleeping except checking for a touch input every x miliseconds

same question here :slight_smile:
..and worst, with 6.13 (see changelog) disabling LCD has less results (AFAIK)
