<div>So, varnish memory usage will mostly come from
three directions:</div>
<div>- storage, include Transient, so check the
g_bytes fields in varnishstat. Passes and shortlived
objects will use Transient, so you can either reduce
those, or limit the Transient storage (unbounded by
defaukt).</div>
</div>

Checked the g_bytes for transient in varnishstat. It's in
Kbs. <br>

<div><br>
</div>
<div>And no, no way to modify the mmap without
restarting varnish.</div>

<div>May I ask how much data you are caching?</div>

Could you please let me know how to figure out the amount
of data cached?<br>

<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>
<p>Pinakee<br>
