Based on the log file, I think these are the relevant portions:

2012-08-29 12:42:47: Scheduler Thread - In the process of canceling current tasks: ignoring exception thrown by render thread 0What they seem to show is a Deadline issue causing a task to be cancelled (Scheduler Thread - Cancelling task because task filename “\server-2\deadline_5\jobs\007_100_999_3d294db1\tasks\007_100_999_3d294db1_00005_6-6.Rendering.Ibm002” could not be found) and then there is some sort of problem cancelling the task since we don’t see another job pick up until 50 minutes later.
Can you confirm that this is what you mean when you say it hangs? There were jobs the machine should have been picking up during this period right (ie. the job list wasn’t empty)?
