Simple math.

If you have 80 processes, and each take 4mb of RAM, that's 320mb usage
on a box that only has 384mb total -- your OS and other overhead apps
are going to take a little bit of that.  If any of those 80 processes
hog up more RAM, you're going to have troubles, especially if they're in
the 32mb range.  How much swap space to you have configured?
