It sounds like your database handle $conn is going out of scope before you properly close it. You are explicitly disconnecting $conn when you're finished with it right?

Even if you are disconnecting, you will still get a warning about an outstanding, uncommitted transaction, if you haven't performed a commit before you disconnect. You may want to specify auto-commit when you open the database connection (or at least be aware of its setting):

$conn = DBI->connect('dbi...', $user, $password,
                      { RaiseError => 1, AutoCommit => 1 });

It is difficult to say anything more without more information to go on.

Updated: Changed AutoCommit value from 0 to 1
