dissolve is distorting geometry

Running ArcMap 10.1

 

I am using the Dissolve tool on a polyline shapefile, dissolving on two attributes (not sure if that matters).

 

The resulting output always contains small geometric distortions. It appears that not all of the vertexes are being carried into the dissolved linework. If I reduce the number of input features (subset the geographic extent) the situation improves, but does not go away.

 

Is this a bug? Any solution? I was hoping to rely on this tool but with this happening, it's just too risky.

 

Thanks!
