<div>After updating from BIND 9.9.4 to 9.9.5 we started to experience failures on DHCP 4.2.5-P1</div>
<div><br>
</div>
<div>Once where the dhcpd process would hang, and become unresponsive after +24hrs of running. Then once again after ~12hrs of running without issue, dhcpd process crashed completely. Both times had no indication in dhcpd logs of similar behavior pre-unresponsiveness,
or other logs indicating either unexpected behavior or other failures/errors. No indication in BIND logs either.</div>
<div><br>
</div>
<div>Rolling back to BIND 9.9.4 resolved the issue. </div>
<div><br>
</div>
<div>Have so far been unable to reproduce this in a test environment, nor have we had the ability to turn on debug logging in production environment (yet.)</div>
<div><br>
</div>
<div>Even though it was an upgrade in BIND, posting here since it was dhcpd that was crashing.</div>
<div><br>
</div>
<div>Any insight as to why this may be happening?</div>
