Are you swapping? Insufficient memory causing the OS to swap processes
out is the only thing I can think of that could cause this. You
usually have to be *REALLY* low on memory (like a 512MB process on a
128MB RAM system) to cause total unresponsiveness, though. Try adding
more RAM or limiting mysql's use of it by lowering buffer sizes in
my.cnf.
