Who crashed and why?

From the manager's log:

From the render node's log:

[26/August/2014 13:55:37] New job order received

The node that crashed (but was it the node, or maybe the network or the manager or the licensing PC?) picks itself up and automatically rejoins rendering, which adds time to the ongoing job, which, in turn, delays the next pending job.

It would be good if the last "good" MXI of the crashing node would be saved and the next pending job started; that way one could manually merge later. The way it is now, the crashed node restarts its contribution at SL 0, which, in case of a crash just before the rendering is done, effectively doubles the specified rendering time. And cooperative renders always crash just before they're done

What is the right method to find out the root cause of a crash?

Thanks!

Bump...

Maybe this is easier to answer: if one sees "Application error" in the Windows Event Viewer (I tried rendering locally after pack & go) and so there is nothing in Maxwell's log - how can one get to the cause of MR crashing? Here's the details from the Event Viewer:
