I have a mac mini running OS X Server (Mavericks, 10.9.1 - latest Server.app) and I keep getting these error messages in them system logs every few minutes. I am not sure if there is a real problem or not.
Jan 22 08:20:54 myosxserver.com ntpd[???]: unable to create socket on en0 (????) for ipv6here
Is there really something wrong? or can I disable ntpd from logging these?
