What's MDworker

[fireshot91]

I saw that for the last couple of minutes that iStat's menu bar showed my CPU being at a full 100% usage.
I closed the flash game I was playing, and it went down to about 75%.

I checked the active processes, and iStat showed mdworker using about 90% of my CPU.
Any problems?
Google shows that it should be at the most around 40%. The only thing I have mounted is my boot drive, and Time Machine. Oh and a DMG file.

My active applications are my wireless card application, Transmission, iTunes, Firefox, and iChat.

"MD" stands for metadata -- mdworker is part of the suite of tools that provide the Spotlight functionality. Every once in a while, people find it pegging for no reason... usually the recommendation is to manually force a new spotlight index. this might help:

It's pretty much Spotlight. Have you added new files, a new volume, or reinstalled OS X lately?

Yes, I have added new files.

Now it's not doing that, it's not even in the top 5 tasks anymore. I guess it was because Time Machine was backing up? Or because it was indexing my drive.

Oh well, all I know is it's gone now!

New files and indexing Time Machine would definitely do it.
