Kernel Panic - Should I be worried?

[dmetzcher]

I was just playing World of Warcraft and got a kernel panic. I haven't had one since last year when I had Norton Utilities installed. I hasn't happened again, but my connection to the WoW server seems to be acting weird.

Should I be concerned, provided that it doesn't happen again when I am not using WoW?
How can I look at the log to see what may have caused it? Is is possible to know what caused it?
What should I look for in the future (just in case), if this is hardware- (and not software) related?

Also, I had two FireWire drives connected. Is my data OK after a kernel panic (I rarely disconnect drives without ejecting them)?

Thanks to anyone who can provide a little help.

It happened again...this time while I was attempting to do a "just in case" backup with SuperDuper. Also the machine was sitting, powered on, for about twenty minutes, and got pretty hot (hotter than I have ever noticed before), because I was a moron and left the room while the backup was running (and when the kernel panic happened). I've rebooted and am going to try to do a full backup again.

Is there anything that I should do right now?
Any tests that I can run?
Anything that I can look at?
