We have a 3G P4 with 2GB ram box, RouterOS 3.10 and Userman package.

The box is not under heavy load yet the CPU load goes up day by day.

The box is currently acting as Userman radius server for pppoe clients who
connect to pppoe servers set up at each node.

The box also does NAT for every pppoe network from the different nodes.

Right now, we don´t have more than 20 customers... so there should be
no load problem..

If I reboot the server, CPU load starts low and the gradually gets up again.

Here is a graph of CPU from boot up a week ago.

Anyone having a similar problem or any thoughts as to what might be causing it?

Regards,
Santiago.

I have a cpu issue on 3.10 aswell.
Only started when we upgraded to 3.10.
But this is on a routerboard 230.
I have also seen it happen on the 500s aswell.
Reboot fixes it for a bit.

PPPoE server ~50 users

My problem was solved. It was quite stupid actually.

My routeros had a dude package installed that was doing lots of traffic.

You should try and deactivate any unused packages.
