Summary:                    Bad locking logic on res_config_mysql.c
Description: 
store_mysql calls find_database(), which locks the database handle.
Then, it calls internal_require(), which calls require_mysql(), which
calls find_table(), which calls find_database(), thus requesting a new lock
on the database handle.
I could be wrong in the call chain, but the result is always the same:
Asterisk stops waiting for a lock to be released.
