Failed to run request [UPDATE Task SET attempts_left = attempts_left - 1 WHERE id_task = ?]: no such table: Task(1)
This can be reproduced fairly easily on some powerful machines by launching some tests in a loop:
while [ echo $? -eq 0 ]; do ./samples --gtest_filter=SamplesTests/ResumeTests.Parse/attached_subs; done
On my machine the test ran nicely for about an hour before I stopped it.
