Description of problem: This appears somewhat similar to rhel7.3 bug 1376942. I don't see this every time but I have seen it quite a few times now in rhel9.0. It's likely a timing issue, I'll attempt to debug this more and add additional information.

Another reproduction of this issue. This appears to be some timing issue, as this is not 100% reproducible.
