Workernode is running 24.0.3 and submitter node running 9.0.17 (again version should also not cause any issue)
We stopped supporting 9.0 quite some time ago, and I can't reproduce the problem locally; I don't know what to tell you. You could try wrapping the `Osversion` expression in `debug()` and adding D_FULLDEBUG to the negotiator and schedd to see when it's being evaluated and to what.
