While searching for the culprit that is responsible for the AirTunes cut-outs, I thought it might be a good idea to try disabling Spotlight and Dashboard.
Two steps are necessary, first turn Spotlight off in the
hostconfig file, then disable indexing and remove the existing indexes with
> sudo vi /etc/hostconfig vi> Go SPOTLIGHT=-NO- vi> ZZ > sudo mdutil -i off / > sudo mdutil -E /
You can then use Activity Monitor to kill any
mdimport processes or else just reboot.
If you later change your mind and decide you want Spotlight after all, it's easy to reactivate. Set
/etc/hostconfig, run in Terminal:
> mdutil -i on /</pre>and reboot.
To turn Dashboard off:
> defaults write com.apple.dashboard mcx-disabled -boolean YES
To turn Dashboard on:
> defaults write com.apple.dashboard mcx-disabled -boolean NO
You have to restart the Dock after making either change for it to take effect:
> killall Dock
(NB. Neither turned out to be the culprit for AirTunes. It was the broadband router which dropped more and more packages until it died a couple of months later.)
