Problem after update to latest rolling

Hello all ,

I have upgrade yesterday one of my 2 route reflector servers from rolling 1.2.xxx to latest 1.4-rolling-202102130218 . It seems that it start to have packet loss every 30-40 icmp packets . In the logs i see the below event ,

Feb 15 14:09:00 ef-1-routeserver2 ntpd[2015]: routing socket reports: No buffer space available

Any ideas ?

Hello @merlinios, is it bare-metal or VM? Could you show configuration?

show configuration commands | strip-private 

It is a bare-metal installation ,

Could you show an output of the command sudo top and press 1
Also, it will be interesting to get NICs information

show interfaces ethernet eth0 physical 
show interfaces ethernet eth1 physical 
show interfaces ethernet eth2 physical 
show interfaces ethernet eth3 physical 

And check sudo dmesg output, try to confirm that this is not conntrack table overflow issue

Ofcourse no problem

Can i revert to previous version without having any problems ? I have a lot of complaints and no time for troubleshoot unfortunately

Thanks

Sure you can, use operational mode command

 set system image default-boot vyos-1.2....

and reboot router

I guess the main issue related to i40e firmware and i40e kernel module, but on the other hand I see high cpu load by frr components, like zebra, mpls, etc.
