Kristian> Would be really great if someone could take a look and fix this. first problem: Have no clue how the general_log could say its in use. This comes from table->in_use, which should be 0 if the table is not in use by another thread. I spend some time looking at this, and in_use should be reset by previous statement in close_thread_tables(). If this happens again, we should file a bug report to MySQL; If they are not fixing this, I will take a look. Second problem: Don't know if it's defined in which order the tables are in 'show open table' so the second test is bogus. (In theory it should be a defined order based on hash values, but apparently it isn't) I think we should change the code to use: show open tables from test Which should fix it. I noticed that in 5.1 they have 'fixed' this by removing a lot of SHOW OPEN TABLES test, which I think is the wrong fix. What they should have instead done would be to add a --sort-result line to mysqltest.c Regards, Monty
