Client paid with success but no order was created in magento 1.9

[moog123]

A client tries to placed an order and paid with success but no order has been created in magento 1.9. 

We checked our paypal account and confirmed that we did receive the payment. Could someone tell us anything we should do to prevent it from happening in the future? Thanks!

Error message was "Internal Error (#10001: Internal Error). " fromexception.log and here's more detail in the log:
