my whole computer pauses momentarily

[OraliusJohnosn]

i'm worried, i just repaired my hard drive with diskwarrior yesterday, because the directory graph was a mess. after the rebuild there were still a few spots on the graph that were out of place. now when i'm computing i have moments where everything freezes for less than a second including my itunes music that is playing. its happening ever 5 minutes or so.
i have a:

mac pro 2 x 3ghz quad core
with 4 gigs or ram
my audio card is a mbox

Try checking the drive with SMART Reporter fault codes: http://versiontracker.com/dyn/moreinfo/macosx/23232

Also, try repairing permissions and disk structure with the Disk Utility. And check the Console for any warning messages.

Why did you have to repair your drive with DiskWarrior?

cause i checked it and it said the directory was a mess

smart reporter said it was clean... i repaired permissions. console reads this over and over again

mdworker is part of the spotlight indexing service. I'm not aware of an easy way to repair it, but perhaps an archive & reinstall of the operating system will be the simplest solution.

I've just had this problem, exactly, and the cause turned out to be the Spotlight indexing process. Fortunately, this can easily be disabled, and my system returned to normal.

I've detailed my experience, and resolution, on Apple's Discussion site: http://discussions.apple.com/message.jspa?messageID=11087388 hope it helps!
