Multi-processor render crashes

I'm rendering a long (5750 frame) project on an 8 processor Mac with 16 gigs of ram running Windows 64 with AE CS3. I have multi-processor rendering turned on but I can't get through a render without a crash.

what's the format of the drive that you are rendering to? if it is fat32, then i think you have a single file size limit of around 2-3gb... if your 5750 frame project is rendered as uncompressed sd, that's a 5.75gb file, so that may be the issue... particularly if it is crashing at about the same point each time...

Thanks for your reply Kevin. I must confess I do not know if the format is fat32 as I'm new to this workstation. I will say that when disabling multi-processing in the preferences the project renders all the way through. And when attempting to render with multi-processors it crashed as early as from 1600 one time and as late as 5100 in another.

fat32 would be a fairly common format for a drive that needed to be accessed by both mac and windows... since you are running windows on a mac, it seems possible that the drive may be formatted that way to allow it to be used by either os... (also, max file size is 4gb... makes sense, 32-bit addressing would be 4gb....)
but since the crashes are a very different points, it's likely that there is another problem... there was a fix in the 8.0.2 update for machines with more than 4 cores, so make sure you are running v8.0.2.
even with 8.0.2, i have had a few projects that have had to be rendered with multiprocessing turned off... they were older projects (like v6 or 7) that were rather complex... i had originally blamed third party effects, but it could have been ae itself...
you might try decreasing the max ram cache settings a bit (preferences>memory and cache), the default is 60%, you might try 35% or so just to see if it may be a ram fragmentation issue or something.
also, there is a forum here for running windows on mac, you might post there too... they may have some good input.
