Hello,

I've got a problem with my four Mikrotiks RB433. Since I turned on NV2 protocol devices randomly reboot. Sometimes is once per a day, sometime couple of times in few minutes.
Any ideas why this problem appear?
In attachment an image with example from log of one RB433. This is the worst.
Please help me.
Regards,
Andrzej

OK. I will send. Thanks.

Have you reloaded the OS?

Yes. I was upgrading RouterOS and firmware. Many versions. This wasn't solve the problem.

I wrote an e-mail to support. I got an answer that is problem in too weak power supply.

looking at the support output files the kernel failure cause be caused because
of the PCI interface crash which usually is caused due to insufficient power.
What wireless cards are you using and what power supply you are using?

I had 24V/1A power supplies that I replaced to 12V/2A.
Problem solved.
