What sort of allocation errors? Can you post the text? You should NEVER see an allocation error in 64bit Max. Does this mean you are running 32bit Max? In that case, it is entirely possible that you are running out of memory. In 32bit apps, there is only 2-3Gb of memory space of which Max itself can eat up 1.5Gb.
So I guess it would be a good time to figure out the specs of your machine (8 core beast right?), avail memory, max version, etc.
