<p class="MsoNormal">We have recently made some major changes to our DNS infrastructure. This involved consolidating servers and standardizing on a single RHEL6 platform. We currently running the latest RHEL6 packaged BIND release of 9.8.2 (9.8.2rc1-RedHat-9.8.2-0.10.rc1.el6).
Lately on one of our busier names servers the named daemon has been crashing with assertion errors. Here is a recent log snippet:<o:p></o:p></p>

<p class="MsoNormal">I did a little research and found a few forum posts where others were having the same or similar problems and the general consensus was that this was a problem that was fixed in 9.8.2. Apparently my problem is slightly different or the
issue wasn’t fixed. <o:p></o:p></p>

<p class="MsoNormal">Is anyone else having this problem, and if so what did you do to remedy it? Also, I have the coredump. Where should I send it for further analysis?<o:p></o:p></p>
