title: Did not see 20 I/O Cycles; giving up occurring in Swift when downloading audio files
body: <p>I'm doing some maintenance on some code (unfortunately I didn't write it, so I'm still trying to figure out what was done in this project), and the app downloads several hundred audio files and allows users to play them.</p>
  
  <p>When I attempt to play some of the downloaded audio I'm getting an intermittent bug with the response: </p>
  
  <blockquote>
    <p>ERROR:    >aqme> 236: Client(0x7fb329c2ba00) did not see 20 I/O cycles; giving up</p>
  </blockquote>
  
  <p>Whenever I get this error the audio doesn't play. Does anyone have any insight to what this error means? How to debug it/ideas on what to look for? I haven't found any other stack overflow posts with this bug. Thank you. </p>
