QSqlDatabase, MySql, Threads and Debugging environment

[Hawkeye64]

I have some code that creates a number of runnables using a threadpool to access different tables in the database. These all work when not run from the debugger, when compiled in Debug or Release mode. But, if I run from the debugger these all fail. Keep in mind, this all works when NOT running from the debugger. So, the debugger is causing some interaction issue. Would anyone have any suggestions as to why this is happening?

Here are the specific errors:

"Database Error(2013): Lost connection to MySQL server during query QMYSQL: Unable to open database 'myDatabase'"
"Database Error(2013): Lost connection to MySQL server during query QMYSQL: Unable to open database 'myDatabase'"

Do you correctly open and close the database connection in each runnable?
Does each runnable use a unique enough connection name?
