<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>
