Hello, I’m on a 2x Quad Core Intel Mac pro with 32gb of ram, running After Effects CS4. I have multiprosessing enabled and I’m working in adaptive resolution. I do extremely heavy 2.5D comps. The system has been great so far but I’ve been having problems occasionally on my exports. I go through the render cue set all my settings to my likings and hit render and also enable caps lock for faster render.
Usually when I export it’s quick and fast with all 8 cores using 3gb or ram each, when looking at the activity monitor you can see the ram is maxed out and everything is quick. But for more complex comps i’ve been finding that the export starts out quick

with an estimated time of 10min lets say, and all cores utilizing the max amount of ram, then about a quarter into the export the estimated time shoots to like 30min to 40min and suddenly the ram usage suddenly drops almost completely.

In other words it’s like the multiprosessing or cores stop working I guess.
Is their a reason for this to be happening, I’m trying to figure out if this is a software bug or if it’s a system thing, has anyone else had such things happen? It seems to happen for more complex and heavy comps.
Many Thanks in advance.
