Error in my_thread_global_end(): 7 threads didn't exit

Hi,

I'm using the Red Hat Enterprise Linux 5 (non RPM package) C++ connector to connect to a database in a separate thread created with pthread_create:

void* CDatabaseConnector::WorkerThread(void* arg)
{
CDatabaseConnector * me = static_cast<CDatabaseConnector*>(arg);
long long status = 0;
//pthread_mutex_lock(&(me->_WorkerThread_mutex));
LOG(CLogger::Debug, "CDatabaseConnector" );
try {
sql::Driver * driver = get_driver_instance();
/* Using the Driver to create a connection */
std::auto_ptr< sql::Connection > con(driver->connect(me->_sql_settings.host, me->_sql_settings.user, me->_sql_settings.password));
................

Everything works great but when I close my application I get the dreaded :
Error in my_thread_global_end(): 7 threads didn't exit

What I figured out is that the number represents the number of times I opened a mysql connection with driver->connect().
I'm not sure what should I do. The application I am writing is meant to be highly reliable and is meant to be running for days or even months without stopping, so probably I can't ignore this issue.

There seems to be no issue with Windows and Mandriva Linux, I guess its something wrong with RedHat binaries.

Regards,
Constantin Cristian
