After 40% a render plunges and stalls out

[BadRobotProductions]

Hey Vlado,

Any clues to what may cause a batch render to completely die out after 40% and stall for over 8 hours?
I know this is very vague but essentially there are no errors or anything of the sort..the render just stalls.
The processors go from 100% load to idle and the render just sits.

No errors come up in the report.
All machines are 24 core with 24 gig of ram.

UPDATE: Looks like something changed between builds that is causing the issue. Guess I can't revert!
ah well.

There was a particular change that could cause this; I should be fixed in the latest builds though.

Best regards,
Vlado
