Magento EE 126.96.36.199
We have two production servers behind a load balancer. Session persistence is maintained by the load balancer so you stay connected to the server while making an order. Normally the customer enters an order and receives an order confirmation email sent by that same server. A few days ago both servers started sending order confirmations. Literally nothing has changed on the servers except the addition of a few products and new customer orders.
Anyone else seen this before? Any idea where to start looking for a solution?
Have you confirmed that the cron has not been enabled on both servers (It should only be enabled on the Master content server)
What did Magento say when you opened a support ticket?
