            This is the same root cause as LU-12404, namely the patch from LU-11760 allowing too many objects to be created, which is what test_69 is exactly trying to detect, but it was skipped because it is in the SLOW group (about 10 minutes per test).

            While the test doesn't give enough output for me to be sure, I suspect the culprit is LU-12396

            (For a lot of ZFS failures)
