Hello,
In current project I faced with situation that looks really strange for me and I have found nothing over the Intenet. Our Async Service crashes with following exception every 5 mins.
Host SRV-CRMBE-EN-02: failed while monitoring asynchronous operations queue. Exception: System.ArgumentException: An item with the same key has already been added.

Has anybody seen similar behavior? May be you can share some info regarding troubleshooting of similar issues with Async Service?
