title: Azure Queues dequeue count growing with Rebus core
body: <p>I am using Rebus (<a href="https://github.com/rebus-org" rel="nofollow noreferrer">https://github.com/rebus-org</a> (v.5.3.1)) and until now everything has worked out just fine for years. (we upgraded from core 2.0 to 3.1 a couple of weeks ago)</p>
  <p>For the last couple of days, it had a lot of messages that just grows in the &quot;dequeue count&quot; column. we use Azure storage queue. The que handles the other messages as it should, but we still got 6000+ message with dequeue count higher than 250 in this moment.</p>
  <p>I can’t really find anything that looks off, and it doesn’t add any rows in the error que.</p>
  <p>I have tried to restart the server, so the Rebus is totally restarted but no luck</p>
