Where do we provide feedback about application crashes?
Do you have a specific site for bug reports?

In my particular configuration it runs for upwards of 2-3-4 hours then it crashes.

I will turn on minimal logging to get more specific details captured.

I believe it has been happening with beta 5 and 6. sorry for not having more detail. I have only just today turned on first level of logging.

Here is more detail. It just happened again this morning.
