The problem occurs when 2 people place an order for the same item when the stock level is low. When 2 orders are placed very close together they are both allowed to check out the same item.
If there is 1 left in stock and they both check out too close together both checkouts complete correctly, the result being you have sold the same single item twice.
All the stock control options set to not subtract stock and not allow checkout.
I haven't witnessed this myself, I have been told by a fellow zencart user that they have seen the same 'bug' on several occasions on their very busy site and have not found a solution here.
I have searched and not found anything in the forums.
He's using an unmodified install of zencart (version 1.3.8 I believe).
I've used zencart for a number of years on a quieter site, but this week I'm launching a new site which will sell out 1 product, 100 in stock in less than an hour, and I'm really concerned we will hit the same problem and sell more than we have stock for.
Can anyone tell me if this is an issue that has been raised before? Or been fixed? or anything?
Thanks
