Recently I had a scenario where I activated Ordered Delivery on a send port. To my suprise - after I sent about 100 messages through the send port - one active instance of the port remained in admin console. I was able to terminate it but after sending some new messages through the port, the active instance appeared again. Seems that this is by design - but I'm not really sure. I couldn't find any information about this in documentation or online. Does anybody know this behaviour
