title: A bunch of error "An error occurred using a transaction. " in serilog file
body: <p>Serilog tracks a bunch of errors repeatedly with the below description:</p>
  <blockquote>
  <p>An error occurred using a transaction.</p>
  </blockquote>
  <p>and there is no more detail about where these errors happened. I search a lot to find an answer but no one was helpful to solve.<br />
  Can anybody give me an idea when this error will happen?</p>
  <h2>UPDATE:</h2>
  <p>this error occurs frequently even when there is no request on my application.</p>
