r450 Exceptions

[drpepper]

I have two systems running HG and upgraded to r450 on both and now after some time they become unresponsive. I looked in the console and found a several exceptions occurring somewhat regularly and didn't see them mentioned in the forum search. No custom automation/scripts running on these instances. Restarting the HG service seems resolves it temporarily until it becomes unresponsive again. Might revert to r441 and see if that's more stable. Please look into these.
