Avalon chain dropping hash HELP!!!

[perfectplus174]

I can't seem to figure out why I am dropping hash average when multiple A6 machines are chained.

I have separated them into 2 controllers:

5 on one controller and 6 on the other. I have another controller on the way to split up even more.

My hash rate is dropping to around 2800 gh/s when more than 1 machine is on the controller.

I've seen as low as 1900 gh/s though.

If I restart the machines, they start at 3580 gh/s and then drop from there, some going as high as 4200 gh/s

I've updated firmware for all machines and still nothing.

Here is a screen image from one of the controllers:

I have 20 A6's split on 2 controllers and mine do the same thing. Been fighting this for a couple days now. If I restart cgminer, it runs great for about an hour and then slowly drops. Over 8 hours or so it will be at less than half. If I restart it immediately jumps back up and is good to go.

Someone please help us. So much money being lost. Lol
