Just increased the AckWait from 20ms to 100ms and reduced max
deliveries from 4 to 3.
I believe that there is still the risk that the message is redelivered
while the server is being shutdown and that message is not making it
to the sub.
But using those new values (100ms/3), I have ran 200 rounds on a Linux
VM and did not get the failure (but did before the change).
Again, this is not proper test fix, but may help. This test has been
failing 11 times already (keeping track in spreadsheet) and causes
several minutes of tests to have to be recycled.
Note that the test ran in about 0.4s and now 0.7s, so not that much
and would be worth the added delay if it helps not breaking the whole
test suite!
