In the spirit of more concurring I can also say that we have seen trouble with Analysis and memory on our SUN Blade 1500's (that have 1Gb of RAM) where the CPU crunches for ages. It does seem to clear when the program is saved, killed and restarted but that is if you have the patience to wait to be able to write before killing!
