process ‘snmpd’ is using deprecated sysctl (syscall) net.ipv6.neigh.lo.retrans_time; Use net.ipv6.neigh.lo.retrans_time_ms instead

This error occurred on server with yum-cron installed; So I ruled out updates, but I was wrong. An update solved this issue, ’bout 100mb of updates to be exact… A new lesson learned : don’t blindly trust on yum-cron!

As to this error I believe it was solved in one of these packages :
