I can't start https://quarry.wmflabs.org/query/15564 any longer, the "submit query" button doesn't work. Feels like a limitation of lines or chars had been implemented there. Well, my query is a bit voluminous but a run takes not much time as one can see. A comparable query https://quarry.wmflabs.org/query/39167 runs fine.

The web node (not the database node) ran out of disk space right before Nov 12. Might be relevant. Let me fix the disk space issue.
I cleaned the files. phab:T238375. Could you test if the issue is fixed?
@Zhuyifei1999: Runs well now, thank you very much!
