My design failed, but I can't tell why. My only guess is that this has something to do with it:

DRC space fail: [0x1a298d0 0x1a2ad50] 0.004093 - 0.006000
DRC space fail: [0x1a29970 0x1a2ad50] 0.002715 - 0.006000
DRC space fail: [0x1a29a10 0x1a2ad50] 0.001996 - 0.006000
DRC space fail: [0x1a29ab0 0x1a2ad50] 0.001850 - 0.006000
DRC space fail: [0x1a29b50 0x1a2ad50] 0.001996 - 0.006000
DRC space fail: [0x1a29bf0 0x1a2ad50] 0.002715 - 0.006000
DRC space fail: [0x1a29c90 0x1a2ad50] 0.004093 - 0.006000
DRC space fail: [0x1a2ad50 0x1a298d0] 0.004093 - 0.006000

I'm sorry I don't have an answer for you because I get the same thing. I'm guessing we have some spaces less than .006 which is 6mills. I made my board with Eagle and it passes DRC with 8mil limits.

Yep, there were some gaps too small. I figured this out by inspection--just looking for small spaces. I had a logo that I wanted etched into the bottom layer. Some of the elements were isolated by very small spaces. I think the Eagle DRC didn't complain because it was all the same signal, so bridging wouldn't matter. The logo was a creative commons (CC). I just ditched it and then my board passed.

Thanks "kwknowles" for your help. I too was getting two of these "space fail" errors and did not know what it meant. After reading your post, I looked at my design and sure enough found one pad / track space that was only 0.004. I corrected it and the board passed DRC.
