I had the exact error and situation occur the other day. The customer
called in and stated that the system (IC) actually told them the
transaction was denied and wondered why. In 4.9.7 IC actually produced a
new order number when the user submitted a second time it went through
(no dupe order but should have been).

I am not even sure my self what caused the error, but for some reason at
the same time this occurred the logs had errors in it stating it could
not speak with the sql server. After a restart on IC all was well. 

This was weird and thought it to be a isolated incident, like one of
those problems the only way to produce is if your hair was suddenly
orange, you have to stand on one toe and put your finger into a light
socket and finally your name has to be Velcarcha Domanta. OH Well I was
wrong.
