double orders, double billing

[rich89]

I've had 7.3 running for about a year with few problems. Occassionally I would have a double billing issue, but instances were rare. Of late, I've had 3 double submits out of the last 15 or so orders, one of which was a COD order. Other contribs I have running are Featured Product, a calendar script to set a time and date of delivery, VVC, and PriceFormatter (which applies quantity discounts).

 

When double ordering happens, I receive two emails instead of one. The orders each have distinct order numbers & paypal codes. They show up in admin, as well as in my Paypal acct. Checking the time of the orders indicates that the second order is usually placed 25-45 seconds after the first, which makes me think that the order is declined, then placed again, but despite the decline, both orders are going through. That's just a guess at this point. It could also be that server load is causing a long lag and that people are clicking submit multiple times during the lag. Not sure.

 

I searched the forum thoroughly, but it seems everyone else's problems went away once they switched to 7.3, but I've been running 7.3 from the start, so that can't be it.

 

I'm on Godaddy, if that helps, and applied the code modifications in re ports in general.php (I think that was Steve Dallas' fix). Any ideas on tests I can run to determine the cause of this, or a script I can insert to prevent this from happening would be much appreciated. Thanks

IN paypal I think thru some configuration if same order id is posted payal will decline this way You can avoid double orders and paymnet.
