I am sending a message to BizTalk receive location and it is stuck somewhere. Querying the Tracked Message events gives me following:

And when i query all in-progress service instances, i finding my orchestration in state "Ready to run":

The Service details tells me that the message was queued and awaits processing:

In a topic here was suggested that "The message is in an ordered delivery scenario when the preceding message is being retried by the ordered delivery send port."
The problem is that i don't have ordered delivery in my applications.
Thank you for any advice!
