It's called a kernel panic. If it doesn't happen again, or very infrequently, don't worry about it.
In most cases, kernel panics are not caused by an issue with your Mac. They are most likely caused by an issue external to your Mac. If the kernel panic doesn't happen again within a few weeks, you don't need to troubleshoot further.
"You need to restart your computer" (kernel panic) message appears (Mac OS X v10.5, 10.6)
Mac OS X 10.7 Help: If “You need to restart your computer” appears

Also, you may have better success in attracting responses to your thread, and you'll make your thread easier to find for those browsing the forum for the same answers, if you follow this tip.

Did youy have any kind of USB sound device attached? Like a third-party webcam, microphone, speakers, or sound card?

I don't really know much about how to read kernel panics, but having a quick look through it, I see the mention of hamachi.

My mini has only ever had 1 problem with kernel panics, and hamachi is what caused it for me.
