Hard Drive Space decreasing to 0 KB?

[Caturday Yet?]

Running Snow Leopard on a Late 2007 MacBook, and I booted it up today to see that I had 15 GB left (normal). 4 hours later, I get an alert that I'm running low on Hard Disk space, so I open a new Finder window to see how much space I have. It tells me 10 MB.

After 5 minutes, this dropped down to 0 KB, and all of my applications opened "paused", and I had to force quit them.

I don't have 0 KB left, I have 15 GB, but Finder isn't telling me that. Is there any way I can fix this?

might be a runaway log file.

You'd need to look at the runaway file and see what error messages are showing up. Usually some application is doing something funny and writing error messages over and over. You'll have to find the file and see what's in it. Might also look to see what apps are running and if you've updated them recently.
