Thank you Stefan,
had to remind myself of the versioning. receptor binary is based on devel, so that is why you have the git hash in receptor --version. This is expected
I have noticed these errors as well, and I believe they aren't necessary a problem.
That said, I think it is a bug in AWX, maybe our reaper logic is trying to cancel/release work that doesn't exist.
Would you mind opening an issue in AWX describing the problem? We can then prioritize looking into cleaning up the logs
