This particular case should be rare. It looks like the build task was restarted on a different host, and the restarted one failed early due it a bug in the wait() function that was fixed by commit 73f325e . Unfortunately the restarted task failed before it knew there was even a build to fail (it was still sorting out the srpm).

I'm not 100% sure what to do with this. I don't think task restarts can be perfect. The root bug that triggered this should be fixed by the commit I listed at least.

So, going to close this for now. If you find more instances with that fix applied, please let me know
