Advice that helped me...
I was having a very similar issue as described here. I only had 20 to 50 GB free, but I have had much less than that free in the past with not nearly the problems I had seen in the past week and especially tonight - until, that is, I followed some advice I found in a different thread. The advice was to open up the disk utility and repair permissions. That has helped tremendously so far, and I hope it continues to do the trick. I also hope that this advice will help some of you.
