your intensity is TOO high, and your cards dont keep up. Lower it!
How is an intensity of 20 to high? I have all my cards set to 20 and they run perfectly fine and with less than ~2% rejects as well. So I really doubt that is it.
Intensity of over 13 in cgminer ususally gives less hash rate. Try 13 for an hour and see if it helps, I bet it does.
As far as the error, we rebooted the servers for like 3 minutes around that time, sometimes cgminer gets hung up and doesnt properly reconnect when the pool goes down. Just restart your miner (try -I 13 Trust me, its worth trying) and it should be fine.
I belive the problem is gone now! I must have looked at the screen at exactly those 30 sec

Anyway, seems like its working better and better. But i have some problems with Reject's, for the last 12h my stats are the following:
A: 7993 R: 220 HW: 0 , thats about 2,7% rejects. I have tried I=13 but that gives my way lower rates, about 250-280Kh/s per card which is like 50% of their potential rate? Any ideas?
Thank you!
