strange system log entries

[alexs]

Running 10.4.7 server--the machine is connected to a router, and has an internal address only.

 

every 30 minutes I get this in the console and system log:

 

Aug 25 23:44:55 darkstar servermgrd: servermgr_dns: no name available via DNS for 192.168.150.2

Aug 25 23:44:55 darkstar servermgrd: servermgr_dns: no hostname set and unable to detect via DNS, services may not function properly - use changeip to repair

 

 

any ideas how I can keep the logs from filling up with this junk? everything is working fine. this is just annoying. thanks.
