Usually when I see this set of messages and both Graylog servers are in fact up, the time is wrong on one or both of the servers. Make sure that your ntpd.conf on both servers is pointing at the same ntp server, and to see whether it's actually sync'ing, stop ntpd and run ntpdate against the ntp server. If ntpdate claims it's adjusting the time by any significant amount on either server, your ntpd.conf is wrong. (Don't forget to start ntpd after this if time is not in fact the problem!).
