title: How to avoid "sendmsg()/writev() failed in logger" error in haproxy docker
body: <p>I'm getting this error in the docker logs of my haproxy:</p>
  <pre><code>[ALERT] 135/235942 (8) : sendmsg()/writev() failed in logger #1: No such file or directory (errno=2)
  </code></pre>
  <p>My setup is described in the following question:
  <a href="https://stackoverflow.com/q/67554744/3118613">HAProxy in docker</a></p>
  <p>Can anyone suggest how to fix that?</p>
  <p>Also, how can I view/enable logs of actual accesses to the haproxy and routing activity to the different servers?</p>
  <p>Thanks</p>
