Github Actions CI is unreliable #1934
Description
It seems to be impossible to finish a CI test run. At least one of the jobs will fail with:
Error: Process completed with exit code 143.
A bit of research seems to indicate that this is Github Actions killing the runner, presumably due to hitting some resource limit. However, I wasn't able to find a solution.

This seems to be a problem again. Not every time, but most CI runs are failing because one task or another is being killed with:
Error: Process completed with exit code 143.It's making CI only marginally useful.
We are already running with
-parallel=1. The only thing I can think of to make it less resource intensive is to remove the race detector. But that has been valuable in the past. 🤷[-]Github Actions CI is broken[/-][+]Github Actions CI is unreliable[/+]yavorl commentedon Aug 26, 2026
I began looking at this and noticed commit 93be536. It looks like it resolves it, no ci failures since then.

Yes. I think that fixed it. I forgot to close the issue.
