Server Console Bug

In my server ever since today when I restarted and changed NOTHING the console keeps getting spammed with this message when ever there is someone online, it does not happen when no one is online, only when someone is online. Can someone please help me to stop this, the server lags because of this situation.

SuperRonanCraft Can we get a startup log, and maybe a fill log of the spamming error? Please provide as much information as you can.
