I finally found the problem with our online membership form.  The form includes a CiviCRM profile that has the Drupal user account registration option set to "Give option, but not required."  Users who opted to create a Drupal account during membership signup would complete the form and submit their payment information, then be kicked back to the home page with a Drupal error indicating certain fields in the user registration form were required.  The reason for the error is that we added some custom fields to the Drupal user profile that are required during registration but not supplied when CiviCRM creates the CMS user.

The net result is the payment was processed and a contribution record created, but no corresponding membership record, email receipt, or activity is created.  Here's the bad part.  Since there is no confirmation that the transaction completed, some users go back to the previous page and resubmit the form causing their credit card to be charged again, and in some cases again.

For now, I've disabled the Drupal user account registration option in our CiviCRM profile.  Ideally CiviCRM should be fixed so that users aren't kicked out during form processing when CMS user creation fails.  Instead it should finish normally and post an error on the Thank You page.
