Trying to export a couple of maps on mapknitter but they have gotten stuck in the compositing stage. They are high res (@warren helped me with this a couple of weeks ago). Export seemed to be working fine, and then stuck over the last couple of days. Map is "2020_bean_bed"
thx
Thank you for reporting this! I can confirm that I see the unfinished exports in the queue:
I'll investigate and open an issue with the development team about it!

Thank you @icarito! Please let me know and any advice regarding what caused this issue and how to avoid it in the future would be great.
Hi, just responding to the stalled exports issue; @icarito is right that we are still trying to add more error reporting so this is not as mysterious, but on checking those exports, it seems they are exporting at roughly 0.02 cm/px and that is resulting in a quite gigantic image -- 84743 x 84743 pixels -- so those surely failed to export due to running out of memory. I think in general it's going to be tough to run exports at greater than 10k x 10k pixels -- that's just a really giant TIFF file -- and maybe ~15k x 15k would be the extreme limit.
The extremely low resolution at common (~50cm/px) scales here is still just a result of this being a map of a very tiny real-world area, so it means all our usual expectations about what resolutions will work are just shifted to a smaller scale. It should still work, but we need to figure out what the best resolutions are -- going back to my old response in https://publiclab.org/notes/pataxte/05-07-2020/mapknitter-exports-are-very-small-scale-unreadable#c26803 perhaps something like 0.2cm/px is ideal?
