CentOS7/NetworkManager: Too many netlink events

[Thomas Gutzmann]

I'm evaluating Proxmox with CentOS 7 VMs, and I found some strange messages in /var/log/messages:

NetworkManager ... platform-linux: Too many netlink events. Need to resynchronize platform cache

I googled for this error message, but there is nothing useful to be found. I tested in parallel with ESXi and a native installation, but there I don't see this error.

The culprit seems to be VirtIO. After reinstalling CentOS 7 with Intel E 1000, the error messages didn't show any more.

Has anyone run into similar problems?

Thanks,

Thomas

We also using a lot of CentOS7. Also with networkmanager. But no problem with. I must say we didn'd search for some logs. So maybe we have the same messages in the logs. I think when the system is working normaly you can ingnore the message.

Hi Fireon,

Thanks for your reply. Do you also use the VirtIO NIC emulation?

Cheers,

Thomas

We have the same msg on our servers, but it never caused any problems. It's logged as <info>, so no problem at all

Thank you! As soon as we build the target architecture an purchase subscriptions, I will raise an incident to the support team. Even though it may not be a problem - after some decades in system management I still dislike error messages ;-)
