Premiere CS6 keeps crashing during render

Question

Hey everyone,
I'm currently editing a feature film and is the first time I've edited with Premiere with this amount of clips, going into the thousands. Thus far though, everything was going fine until today when I needed to combine reels to come out with my first rough cut of the film.  From the beginning, I would edit in 3-8 minute sequences to start and by the end of the process, I'd combine them altogether when I needed to make a full length cut for review. For this first cut, it keeps crashing when I try to render more than a few minutes of footage on the full feature timeline and it's running up against a deadline I set.
I shot the majority of the movie, about 95% with the Black Magic Camera and the files were Prores files. There's a few sequences I shot with the Red Epic and they've been on separate 4k timelines. When combining together, i resized them to fit a 1080p output at H.264.
Computer specs:
Adobe Premiere Pro CS6
Mac OS X
Version 10.7.5
Processor: 3.4 GHz Intel Core i7
Memory: 8 GB 1333 MHz DDR3
I know I'm working with aton of files and it could get sticky but even wtih all previous sequences rendered prior to combining them, the system is not cooperating. Even if I'm not rendering, moving the playhead around different clips often ends up summoning the pinwheel of death. Any help please?

Maybe this will help you?
You're using not using CC but I can imagine it works the same on CS6
Prevent crash on export with Premiere Pro CC & Adobe Media Encoder CC
