I am not super familiar with rollups, but there's not a lot to go on here. What version of the stack are you using? What does your rollup job look like? What does the full log show\> ---

Maybe this will help, I have already rolled up my raw data once and it worked without any issues. As a way of testing I am running the same raw files again, and nothing is happening. 'Current position' for rollup is not getting updated, when I execute GET \_rollup/job/raw2diaroll1. ---
