title: Mono WebSocket server freezes for 5 minutes
body: <p>My C# WebSocket server app (with around ~100-200 clients) randomly freezes for 5-10 minutes. Then unfreezes itself. It happens only on Linux while running on Mono. On Windows everything works fine.</p>
  <p>I've found a very old thread with the same problem &amp; solution, but I'm not sure how exactly I should edit the Socket.cs on Mono to fix this. (<a href="https://stackoverflow.com/questions/47477078/mono-app-freezes-at-non-blocking-socket-send">Mono app freezes at non-blocking socket send</a>).</p>
  <p>If somebody could help me I'd be very thankful =)</p>
