<p class="MsoNormal">Hi Team,<span style="font-size:12.0pt"><o:p></o:p></span></p>
<p class="MsoNormal">We are facing an issue with BIND since last 1 year, will you be able to help.<o:p></o:p></p>
<p class="MsoNormal">We have a DNS master and 4 Replicas at 2 sites. <o:p></o:p></p>
<p class="MsoNormal">Current BIND version: 9.9.9.P5 (recently patched to P5).<o:p></o:p></p>
<p class="MsoNormal">Issue: The named process is getting hung or stopped at least once a day on each of these Replicas. This is happening since more than 1 year. Meanwhile, many vulnerability patch versions upgraded and currently running with the latest BIND
9.9.9.P5.<o:p></o:p></p>
<p class="MsoNormal">Temporary Fix: A script is running to check and restart the named process if stopped or hung.<o:p></o:p></p>
<p class="MsoNormal">OS Version: AIX 6.1, TL 9<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Though our DNS master is also running with the same version, we never faced this issue.<o:p></o:p></p>
<p class="MsoNormal">Please Note: all the DNS queries goes to the Replicas and none to the master.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"><span style="color:#1F497D">Thanks and Regards.<o:p></o:p></span></p>
