Duplicate Billing in PayPal Web Payment Pro - Same Error

Over the past 2.5 days I have been receiving duplicate payment through PayPal Web Payments Pro. Various forums say it could be the result of the user clicking the payment button multiple times.

However, I noticed consistent, recurring errors over the same timeframe:

2014-10-22 19:00:33 - PHP Notice: Undefined index: customer_id in /home2/xxxxxxx/public_html/system/library/customer.php(170) : eval()'d code on line 6
2014-10-22 19:00:33 - PHP Notice: Undefined index: payment_address_id in /home2/xxxxxx/public_html/system/library/customer.php(170) : eval()'d code on line 6

3 Questions:

1. Anyone have additional detail on the duplicate billing?
2. Any insight into the error messages?
3. How do I determine what 'line 6' is?

Many thanks.
