Hi All,

I have the following messages every couple of seconds at /var/log/messages:

I’m using AlmaLinux 8 and Webmin and an unmanaged VPS.

Can you please advise me?

Hi Vaclav,

did you find any cause/solution for this?

Anyone ever solve this? @vaclav ? I’ve got the same problem (AlmaLinux 8 / DirectAdmin / VPS). Thanks

Update: for me the fix was to comment the line

net.ipv6.conf.all.disable_ipv6 = 1

in /etc/sysctl.conf and reboot.
