title: Varnish removes objects?
body: <p>I have a problem with varnish server. The main task of the varnish is to cache images. In the configuration, I specified TTL to 365d for images. What I've noticed, after one day I receive X-Cache MISS header. </p>
  
  <p>After doing one more request is HIT, but after a day is MISS again. Why is that happening? The varnish service has 30 GB RAM memory available (100% usage) and uses 45 GB of virtual memory additionally. Images are being removed because of lack of space?</p>
