I'm going slightly nuts here, and would appreciate some additional assistance.

I'm running 3 cubes - 3rd one arrived about a week ago.  2 of them usually run at 38 (high clock) and one of them runs at 30 (low clock) because I don't like how the power leads heat up on that power supply, and I haven't bought a new one yet.

Last Thursday, I was showing 100GH/s at my pool - less than I expected, but reasonable.

Since then, I'm seeing what I consider to be really odd behavior in my proxy(ies).  Specifically, they will run with the usual scrolling display for 10 - 15 seconds, and then stop.  About 45 seconds later they'll start scrolling again.

I've tried Linux (Ubuntu 10.04 LTS and 12.04 LTS) on virtual machines on 2 different hosts.  I've actually lost count of how many iterations of linux machines I've tried.  I've tried Windows XP, Windows 7, and Windows 8 on three different machines - all of which have had the cubes running at 38-39 GH/s each in the past.  I've tried multi-homing the Linux virtual machines - one interface "outside" on the public internet, and the second interface "inside" for the cubes to connect to so as to bypass any congestion that my firewall might be adding.

I've been wanting to blame my ISP (Comcast business - no love lost there), so tonight I built an Ubuntu 12.04 LTS machine on an Amazon EC2 cloud instance, and it is doing the very same thing - running for 10 -15 seconds, and then pausing.  Here's the strange part - the proxy running on the local machine and the proxy running on the EC2 pause and restart at exactly the same time.

Say what!!!???!!!

So I'm officially stumped.

Tonight I'm down to about 13GH/s on the two "faster" cubes, and and about 12 on the slower one.  That's (almost?) not worth feeding electricity to.

I would be immensely appreciative of someone who has some experience with multiple cubes helping me to walk back through this.  I can't believe that it's connectivity issues with the pool - I'd be hearing about it in the forums, right?

Actually - let's explore that for a moment - anyone else here running multiple cubes through Comcast that can say "yea" or "nay" to connectivity issues to Slush?

Thanks in advance;
