>Description:
This test case fails intermittently on some architectures I tested but not all.
Several tests were chosen from the full test suite after observing inconsistent pass/fail results over many runs.
Tests were run periodically from cron, timed to avoid overlapping runs while completing as many attempts as feasible based on the system speed.

The set being reported in July 2023 includes failure rates in the one-percent ranges, to be followed by other tests that fail more frequently.

The results for systems used:

amd64 1506 0
Pi3 271 0
Pi4 790 1
Pi0W 590 7
Pi02W 887 1
i386 (Intel Atom) 708 2
