Error Messages On Shutdown When Using Iguana With MySQL 5.0.45
If you have started Iguana (versions 3.3 to 3.3.2) from the command line, and are using version 5.0.45 of MySQL,
you may notice a problem when Iguana is shut down. After a brief delay, an error message appears:
Error in my_thread_global_end(): 2 threads didn't exit
This error message appears because of a bug in MySQL 5.0.45. The shutdown delay and error message do not affect the performance of Iguana, and there is no risk of data loss.
To work around this problem, use another version of MySQL, such as 5.0.41.
Details on this bug can be found in the MySQL bugs database.
