I just started my first instance of varnish in production. Within 12 hours, there were alerts from our monitoring system that Varnish was taking 90% of the cpu. Right after that, I find these messages in /var/log/messages, several times over a 2 minute period: <br>
<br>varnishd[12461]: Child (20086) not responding to ping, killing it.<br><br>The child restarted, and the stats and cache all disappeared. <br><br>This is a machine with 8 gigs of ram and a pair of slightly older quad core xeons. The storage method is file with a 50 gig limit. At its peak, the machine is serving around 40 requests a second, about 5000k a second. The configs are the defaults. <br>
<br>What should my first steps be to troubleshoot this? Is there a likely culprit? <br><br><br><br><br>
