[Clusterusers] breve segmentation faults on fly

[Chris Perry]

I know we've been rendering fairly hard recently - do the graphs on  
ganglia show a correlation between your seg fault times/machines and  
a lack of RAM on those machines? I would expect a different error  
than seg fault in that case, but it's worth seeing if there's a  
possible connection.
