This test failure and 42a are both intermittent failures that have resurfaced because they were recently temoved from ALWAYS_EXCEPT. Please add them back to ALWAYS_EXCEPT until the test is more reliable.

This failed 3 times while testing the patches for LU-13997 (out of 60 test runs), which had explicit "Test-Parameters: testlist=sanity ONLY=0-418" so the test was not skipped.
