                        <p>Hi,</p>
                        <p>We have been using varnish since more than a
                          year for our ecommerce site. <br>
                        </p>
                        <p>Current version is 4.1.8.</p>
                        <p>OS is Linux. RAM is 8GB. <br>
                        </p>
                        <p>I am observing that the varnish memory usage
                          is increasing (right now 7%) and so is
                          resident memory usage increasing. <br>
                        </p>
                        <p>The storage being used is file:</p>
                        <p>-s file,/tmp/varnish/,${storage}</p>
                        <p>I am not sure about the reason for the
                          increase in varnish memory usage:</p>
                        <ul>
                          <li>Is there a way to limit the varnish memory
                            usage?</li>
                          <li>How can I diagnose what is consuming
                            memory?</li>
                          <li>Most of our web pages have maximum 2 days
                            of cache. Also, some of the pages might be
                            least visited.</li>
                          <li>Is there a way to manipulate varnish mmap
                            (when file storage is used)?</li>
                        </ul>
                        <p>Would appreciate any help on the above for
                          efficient use of varnish.</p>
                        <p>Thanks,</p>
