Mysterious repeat log entries in System events log

I tried unsuccessfully to share internet connection with 2 iMacs without router(That doesn't matter). But after this, my iMac (24" 2.8 GHz) not networked or on internet now shows this repeated log entries every minute:

com.apple.launchd[1] (com.apple.InternetSharing): Throttling respawn: Will start in 10 seconds

This message gets repeated every minute on System events log. Daily, Monthly maintenance was not done automatically earlier today on this iMac (usually it did without any problem) which was on all-night.

I checked with Disk Utility, repaired permissions. Although no problems in working, this continuous log writings disturbs me.

Thanks for any help & Happy New Year!

Best.
