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?

Never happened to me, but I will check for pending workflows and cancel them (if possible), looks like that the async service try to recover the pending jobs and crash, creating a loop.

I would take a CRM Server Profiler trace to see if it gives you more info.
