Your supposed to get that when you join the server with a name too long, a name that is already taken, a name with bad characters in it, and I think with names like "com1" and "CON" in 0.2.2 R3. Sometimes when the GameMode restarts it does this, but not normally. That's a glitch.

The only reason I could think of this happening for no reason is that their is something wrong with your servers script.
