Questions relating to designing PCBs

The DRC bot failed my board for violating the 8 mil trace width limit. My traces are all greater than 8 mils and the only thing highlighted in the picture I got in the email is a single pixel vertical line down the right edge of the board:

any ideas? There certainly arent any components or traces over there... The edge of the polygon is there but I tried moving it away and re uploading but it still failed.

Also definitely no errors on the bottom layer.

edit: heres the log for the top layer:

Hmm, looks like a bot bug. Send an email to the batchpcb guys + they probably will clear the design manually.

What are the circles with the really fine lines in the mounting holes (and 2 other holes)? I've never used BatchPCB before, but I bet they don't let you define holes like that. Why didn't you just put these in the drill file with the other holes?

They're holes made using the Hole command in eagle. The fine line circle is the dimension layer, just like the fine line around perimeter.

edit: but to avoid future problems Ill likely take that advice

Those holes are still in the drill file as well - some CAM jobs just add it to the gerber output. They won't cause any problems.
