2252    MTR's internal check of the test case 'main.mysql_upgrade' failed.
2253    This means that the test case does not preserve the state that existed
2254    before the test case was executed.  Most likely the test case did not
2255    do a proper clean-up. It could also be caused by the previous test run
2256    by this thread, if the server wasn't restarted.
2257    This is the diff of the states of the servers before and after the
2258    test case was executed:
