Creates duplicate order number but no order in cart

[songenterprises]

Here's a weird one.
One of my carts is creating an order with an old order number and sends me the email but when I go to the cart, the order isn't there and neither is the customer.

It has done this 3 or 4 times in the last year and it always uses the same order number - 2006030016 - this particular order number was used ages ago.

Its a valid order but it isn't registering in zencart properly.

Anyone know why it does this and how to fix it?

This cart is 1.3.5

You have zenid in one of the links on one of your sites ...

I am wondering if you have other zenid values on your site(s) and this is causing a conflict ...

NOTE: the current version is Zen Cart v1.3.7.1

Turning on the Recreate Session is a major help ...
This only fails if your hosting site is not setup properly to manage the recreate session ...
