routing process 100% CPU Load intermittently

RouterOS General
1

Hi!

All our RB433AH are having a strange issue.

They are intermittently with 100% load CPU, only rebooting back to normal, but sometimes she did not even respond to the reboot command in Winbox.

In the ‘Tools’ > ‘Profiles’, the process that consumes all the CPU is the ‘routing process’.

RouterOS v. 5.17
Firmware v. 2.39

Any ideas?

Do you use BGP/OSPF dynamic routing in this device?

Hi normis.

We do not use BGP/OSPF.

We’ve tried to disable the packet routing, and even uninstall it, but did not solve the problem.

Of the eleven RB433AH we have, these, two do not have this problem, coincidence or not, these two do not use VPLS, all others yes.

please generate a supout.rif file during the problem, and email it to support@mikrotik.com along with a problem description. We will look if the file shows cause of the high usage.

To me it is exactly the same with a RB433AH, CPU 100% of the routing, and without flowing traffic. And I do not use any routing or BGP / OSPF or VPLS. All basic configuration, I have version 5.14, and also happens to me, could be is the problem of new boards (hardware). Have if it is the solution. Thanks.

Look at the image.

I can immediatelly recommend two things, ibermi. Please upgrade RouterOS to v5.17, and also try to not use MAC address when connecting to the router. Use IP address, it’s much faster and more stable.

Hi normis, we have the same issue with different versions in this ibermi board. We netinstalled it and we had the same problem. It’s a nonsense..

We will try to upgrade to the last version and see what happens and give a report here.

thanks,

if the same happens in v5.17, make a supout.rif file when routing is near 100% and send to support

Ok, but dmagno has it in 5.17 : P!


we only have this as AP, with a bridge. Bridge with wlan and ether. Default gateay and IP in the bridge.


thanks,

Ibersystems, Dmagno, we have not yet received a supout.rif file, please send us for inspection.

11

We are working out today, but next week I will try to send it to you.

I tried doing a supout.rf, but no way has the CPU at 100%, and is unable to create it, leave 30 minutes more, but could not.

Ibermi, how you correct this problem … Because I have the same on one AP.
