<blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;">We have a Bind 9.7.0-P1 instance that is throwing the following errors:<br>
21-Apr-2010 16:59:00.173 general: error: socket: file descriptor exceeds limit<br>

21-Apr-2010 17:00:00.123 general: error: socket: file descriptor exceeds limit<br>

When we try to increase the socket value we are seeing assertion failures.<br>

Restarted named with the option -S 8192:<br>
