IIRC I tried at first but it didn't gave me useful information,
everything looked "normal", then I switched to more invasive
logging including three "ps fauxww" and "ls -l".
On the statistical side over the past three monthes there were 17
occurrences of this issue:

Since the machine runs on average 5 bootstrap+check a day and that ACATS
has 2315 tests, it's a rate of failure of ~ 17 per one million individual test run.
But it's at least one spurious FAIL in about 4% of bootstrap+check.
