Update: Ok, so I FINALLY got to watch what happened when it was in this restart mode.

At about the 56 min mark the miners all stop... wattage drops from it's normal 800W to idling at about 340W.  It stays there until about 58:30 when it restarts and winds back up again about 20-30 seconds later.  So it would appear it's a pool issue... but WHY?  In my config I was pointing both to the same config.  So now I've change to the primary being my BFGminer and the second being my proxy_miner on the same box... diff ports of course. 

So perhaps it's trying to switch pools (why I have no idea) and freaking out when the current and new are the same.  The two ways I'll know is if at the 56 mark I see it's switched to the other server on the admin page.  If it doesn't change and still reboots, I'm going to have to say this is firmware on the blade asking it to do this ridiculous action.
