I've been rendering some lengthy animations lately, myself. No lockups or crashes. That's a refreshing change from my mirror-reflection projects back in Pro Pack, which typically could manage no more than 75-100 frames at a time before going down in flames.

Are you getting quick render times? Got a trick?

Got plenty of memory? Try increasing the bucket size in your Firefly render options. The default is 32, but I often use 64 or even 128, depending upon scene complexity. In addition to speeding up the actual render, it also speeds shadow-map calculations.

Leela hair? Are you going into Futurama withdrawal and making your own episodes?
