<p>Hi All,</p>
<p><br>
</p>
<p>I have been runnig various versions of ISC Bind for a number of years without any issues.</p>
<p><br>
</p>
<p>My current server is a Windows 2012 R2 running 9.3.0</p>
<p><br>
</p>
<p>recently, i have had an issue where bind just stops responding to queries and to get it working again, i have to restart the service. I have changed the logging level to provde debug output and the last thing in the log when it last stoped is below.</p>

<p></p>
<p><br>
</p>
<p>The odd thing is, that i have seen the same error in the log a number of times and the server keeps working.</p>
<p><br>
</p>
<p>Does anyone have any idea what could be causing the server to stop answering queries or suggest any specifiv loggin settings that might help identify it please.</p>
<p><br>
</p>
<p>Thanks</p>
<p><br>
