Hello. My server keeps randomly getting unreachable. I have to power cycle it for it to work again, only to go down after a couple of days again. I thought it was a problem with SSD cache, so I formatted it and made it a ZFS partition as that was a proposed solution for a similar problem I came around, but it is getting worse now. I cannot find out what the problem might be looking at the logs.

 

I have attached the diagnostics report and logs from the syslog server before it crashed. Any help would be really appreciated.

Looks like the crashes are macvlan related.  Switching to ipvlan for docker networks is the easiest way to fix this.   If you must continue to use macvlan then make sure you read the 6.12.4 release notes about this.

I have changed it to ipvlan now. Hopefully this resolves the issue, I'll know in a few days if it doesn't crash. I do use Fritzbox router as mentioned in the release notes my dockers don't seem to have any problems with it so far. I'll update in a few days if everything goes smoothly.

Hey, i guess i got an similar Problem.. but i cant find the Switching Part in Docker Settings anymore.. 

it wont show up... what am i doing wrong

 

There is no Setting anymore. i followed the instructions mentioned in the Release notes.. becouse i got also problems with only IPVLAN..

Don't forget to reboot after the change.
