Hi Connor.<div><br></div><div>As I said:</div><div><div style="color:rgb(34,34,34);font-family:arial,sans-serif;font-size:12.800000190734863px;background-color:rgb(255,255,255)">You either have to little memory in your system or you are asking Varnish to use too much. I'm guessing you are using -s malloc. Remember that there is a 1k overhead on each object stored in Varnish.</div>
<div><br></div><div>This isn't something Varnish does. It is something the kernel does. Varnish might trigger it because of the way Varnish or your system is configured. The kernel uses The Big Shotgun to clear memory and that might explain why Varnish is a bit dazed and confused afterwards. You want to avoid this situation.</div>
<div><br></div><div>So what you want to do:</div><div> - Add memory</div><div> - Add swap space</div><div> - Reduce varnish memory usage (at least if you are using -s malloc)</div><br><div class="gmail_quote">On Tue, Aug 28, 2012 at 7:00 PM, Connor Walls <span dir="ltr"><<a href="mailto:connor.walls@skillpages.com" target="_blank">connor.walls@skillpages.com</a>></span> wrote:<br>
