Repeatedly creating orders

Sorry there is a new problem. During my test payment I received in my e-commerce mailbox an email with the following subject: 
[Order #10] Order Confirmation

Since then, I received a new email every 10 minutes, with the following subjects:
[ #11]
[ #12]
[ #13]
[ #14]
Any of these emails are empty and doesn't correspond to any order (I've checked my Stripe account).

Between [Order #10] Order Confirmation and the following emails I made just one thing on my Stripe account: I refunded my test purchase corresponding to Order 10.

Any idea?

Thank you

LiteCart does not do hammering.

What are the time of creation for these orders? Are they all by the same client ip?

Every 10 minutes, more or less. They all come from the same email address (the default Litecart's administrator email: I don't know how to find ip).
But now they stopped, after 10 emails...

The ip address should say in the table lc_orders or when you edit the order.

The ip address should say in the table lc_orders or when you edit the order. If the ip address is your server itself it was created by LiteCart itself (presumably not). Do you have any add-ons that could save the order, except your Stripe module?
