<p class="MsoNormal">I don’t get this problem anywhere else,
only on this 1 particular DNS server. It has many different
views, and 15x virtual IPs, so I know it is a complex
configuration. My previous version was bind 9.8.6-P1 which
ran just fine. I have read much information, but can’t seem
to put my finger on the solution. I strongly suspect some
type of O/S limit issue, not a problem with the Bind code.<o:p></o:p></p>
