Short description of error

In 3D preview the stitch chain looks ok, but in render time some stitches from the array modifier are missing.
changing the position of the sub surf to after the array can adjust this same as removing the sub surf modifier.

Attached images display the problem well. Is this a bug with the sub surf stack?

Not a bug. It's because of different subdivisions settings for view and render with the Subsurf modifier (1 vs. 2)

I retried this again now - and oddly you are right.

I had however the values set the same levels for view and render and tested it.
Then I moved the modifiers and saved uploaded the file.

Maybe something else caused this?

Subsurf must be shortening a bit the arrayed element, thus a shorten chain (if subsurf is after array, then array works on org element, which is longer).
