Texturing/Coloring never finishes

Hello,

I have a fairly large project (~3000 images, multiple components and multiple focal lengths from 24 to 400mm). When I try to texture (or color) it, it reaches around 1/5 progress, then it just stops (sits at a fixed memory consumption, no disk or gpu activity, and 3% cpu usage). I left it like this for days, with no change. I tried cleaning the model, tried it at different polygon counts, tried to remove some of the cameras, but nothing helps.   
Any ideas?

Thanks!

Hi Kristof,

sorry for the late response.

What were your texture settings?
