Michael, who reported it, was able to bisect it to 6c691b3, which was the first of the series of commits changing job handling. I must note that I had troubles debugging it: I was only able to reproduce the issue in an autopkgtest virtual machine, but not on my normal system nor in a fresh Debian unstable Docker container. I’m considering reverting some of the relevant commits, but it’d be best if we could track this down and get it fixed. The full details can be found at: https://bugs.debian.org/974705 Thanks. -- Cheers, Andrej
