http://localhost:8080/trac/ticket/417 <p> Not sure if a Chris or Jim one. At times over the past few months, images are not always displaying on the site. Seems to fix itself quite quickly usually. But has been more noticeable in occurance over past few weeks. Today though this is an ongoing issue and received loads of emails from staff, vols and users. The images are there in the html, just not showing to the end user. (popups working fine when clicked on). I've just done a clear cache in settings/performance which seems to have helped. </p> <p> Presume some sort of caching issue going on? </p> <p> (also site quite sluggish for editing today too) </p> en-us /trac/chrome/site/TransitionNetwork-Logo-Web-Small.jpg http://localhost:8080/trac/ticket/417 Trac 0.12.5 chris Thu, 20 Sep 2012 15:44:31 GMT http://localhost:8080/trac/ticket/417#comment:1 http://localhost:8080/trac/ticket/417#comment:1 <ul> <li><strong>hours</strong> changed from <em>0.0</em> to <em>0.1</em> </li> <li><strong>totalhours</strong> changed from <em>0.0</em> to <em>0.1</em> </li> </ul> <p> The image issue will be due to caching, specifically which bit of the caching however I'm not sure without spending some time looking into it. </p> <p> If the images show up with https and not http then I expect its the varnish cache -- there is no varnish caching for https. </p> <p> There have been some big load spikes over the last few days -- this will be the reason for the sluggishness, see the munin stats: </p> <p> <a class="ext-link" href="https://kiwi.transitionnetwork.org/munin/webarch.net/quince.webarch.net/index.html"><span class="icon">​</span>https://kiwi.transitionnetwork.org/munin/webarch.net/quince.webarch.net/index.html</a> </p> <p> Specifically look at the general load spike: </p> <p> <a class="ext-link" href="https://kiwi.transitionnetwork.org/munin/webarch.net/quince.webarch.net/load.html"><span class="icon">​</span>https://kiwi.transitionnetwork.org/munin/webarch.net/quince.webarch.net/load.html</a> </p> <p> MySQL: </p> <p> <a class="ext-link" href="https://kiwi.transitionnetwork.org/munin/webarch.net/quince.webarch.net/mysql_queries.html"><span class="icon">​</span>https://kiwi.transitionnetwork.org/munin/webarch.net/quince.webarch.net/mysql_queries.html</a> </p> <p> CPU: </p> <p> <a class="ext-link" href="https://kiwi.transitionnetwork.org/munin/webarch.net/quince.webarch.net/cpu.html"><span class="icon">​</span>https://kiwi.transitionnetwork.org/munin/webarch.net/quince.webarch.net/cpu.html</a> </p> <p> Memory: </p> <p> <a class="ext-link" href="https://kiwi.transitionnetwork.org/munin/webarch.net/quince.webarch.net/multimemory.html"><span class="icon">​</span>https://kiwi.transitionnetwork.org/munin/webarch.net/quince.webarch.net/multimemory.html</a> </p> <p> Apache: </p> <p> <a class="ext-link" href="https://kiwi.transitionnetwork.org/munin/webarch.net/quince.webarch.net/apache_accesses.html"><span class="icon">​</span>https://kiwi.transitionnetwork.org/munin/webarch.net/quince.webarch.net/apache_accesses.html</a> </p> <p> It appears to be that during the load spikes it's only the limit on the number of apache processes (25) that has stopped the machine being brought down by the traffic its getting, however I can't see a corresponding spike in traffic via piwik. </p> Ticket chris Thu, 20 Sep 2012 16:23:05 GMT http://localhost:8080/trac/ticket/417#comment:2 http://localhost:8080/trac/ticket/417#comment:2 <p> Looking at the apache logs it looks like the current load spike is being caused by someone running <a class="missing wiki">SiteSucker?</a>/2.3.6 against the server: </p> <blockquote class="citation"> <p> <a class="missing wiki">SiteSucker?</a> is a Macintosh application that automatically downloads Web sites from the Internet. </p> <p> <a class="ext-link" href="http://www.sitesucker.us/mac/mac.html"><span class="icon">​</span>http://www.sitesucker.us/mac/mac.html</a> </p> </blockquote> Ticket chris Tue, 29 Jan 2013 17:40:08 GMT http://localhost:8080/trac/ticket/417#comment:3 http://localhost:8080/trac/ticket/417#comment:3 <ul> <li><strong>status</strong> changed from <em>new</em> to <em>closed</em> </li> <li><strong>resolution</strong> set to <em>wontfix</em> </li> <li><strong>description</strong> modified (<a href="/trac/ticket/417?action=diff&amp;version=3">diff</a>) </li> </ul> <p> We are migrating to a new server, see <a class="wiki" href="http://localhost:8080/trac/wiki/PuffinServer">wiki:PuffinServer</a> and this will (probably) invalidate this issue, so closing this ticket. </p> Ticket
