My client, for whom I administer Zen Cart, was updating an order from pending to delivered. The customer received 100 emails in a short space of time.

In looking at the database I see the records for at least 50 to the customer and numerous ones to the administration accounts (module order_status_extra). I have tried to replicate the problem on one of my orders with no success.

Has anyone seen this problem? Where else might I look for the cause?

Thanks for your help.
