The job exceeded the maximum log length, and has been terminated.

only in "Vim master" 🤔

But "Vim master" output is 1371 lines, "Vim v8" output is 1435 lines? 🤔

@blueyed do you know how to solve this?

Very odd. I've restarted them, but since the PR and push build failed, it likely will not help.

Maybe some special character that triggers this?
Normally it will allow like 10k lines of output, and no activity for 10 minutes.
