Closing Session Freeze Everytime

[biggerme]

Hello I have a G4 400 running 9.2.2 w/Digi LE w/ 576mb of RAM,I just installed Waves Native Bundle,and I have Stylus running,a RAM hungry program.When closing a session(which I have running some comp. plugs and a few Stylus plugs,my computer freezes,and I have to reboot.I have given pro tools 250 mb of Ram and DAE 100mb and still this freeze everytime,if I go to a session w/out these plug ins it will close so I know it has to do with these plug ins.Thanks for any help.I have done searches and was not able to pull anything up.
