On Debian testing running on core i7 + 16 GB RAM, upgrading 10.5.beta5 to 10.5.beta6 and running ptestlong gives two reproducible failures :

sage -t --long --warn-long 251.0 --random-seed=325458851928711039532352428547385105459 src/sage/rings/real_mpfr.pyx # 1 doctest failed sage -t --long --warn-long 251.0 --random-seed=325458851928711039532352428547385105459 src/sage/libs/gap/element.pyx # 1 doctest failed

The first one has been already reported a few times. Re-running the second one :

Oh, I just put this on https://github.com/sagemath/sage/issues/38760

The second and third are permanent and  have already been reported. Re-running the first succeeds, but the original run leaves open questions :
