Sorry all.<br><br>I didnt notice that I replied for Brandon only, so I forwarded the answer here (and trimmed the config file comments)<br><br>Brandon,
/etc/init.d/pdns dump show some data.<br>
<br>
You should have 2 things: monitoring and more redundancy.<br>
<br>
At first, I suggest you to turn the webserver on. The 1st line will be something like that:<br>
<br>
Uptime: 1.09 days
Queries/second, 1, 5, 10 minute averages: 425, 420, 420. Max queries/second: 454<br>
<br>
With that you know how many queries reach your server. Cache hits is other useful information.<br>
<br>If your load increase, you should use more servers to handle it. You really want a cluster to answer for your NS1.<br><br><div class="gmail_quote">---------- Forwarded message ----------<br>From: <b class="gmail_sendername">Brandon Lee</b> <span dir="ltr"><<a href="mailto:devmgr1@yahoo.com">devmgr1@yahoo.com</a>></span><br>

<div>Hello,</div>
<div> </div>
<div>Recently, our master PowerDNS server load increased dramatically and is timing out in certain areas of the world when servers are performing look ups. For example, an email user reported that they were getting NDRs and delayed reports. After we investigated we come to find that the sending user's mail server was timing out when performing lookups.</div>
<div> </div>
<div>Therefore, we turned on logging by setting the log level to 6 in the pdns.conf file and only on the master server we saw hundreds of queries like below being logged whereas on the slave server this was not happening. Not sure if this is related, but the master DNS server is in high load.</div>
<div> </div>
<div>One thing we have done was changed all our domains SOA record TTL from 3600 to 86400 to see if that would bring the load down and no cigar. Also, is it recommended to run PowerDNS in daemon mode?</div>
<div> </div>
<div>Any help is greatly appreciated.</div>
