<p class=MsoNormal style='text-indent:.5in'>I am curious if anyone has ever ran
into an issue where they are using a ServerIRON XL to load balance DNS servers
but for some reason one of the DNS servers out of X has an exponentially higher
number of connections in show server real <servername> than the other
real servers. This behavior is also indicated by the fact that the CPU load on
that specific server is at 99% and the others are at 11 or so percent.. I also
note that it is ALWAYS the first server in the list which is the exponentially
more used server.<o:p></o:p></p>
<p class=MsoNormal style='text-indent:.5in'><o:p> </o:p></p>
<p class=MsoNormal style='text-indent:.5in'>At first I thought perhaps people
were bypassing the virtual server IP and connecting directly to the real server
IP address but then I realized that there is no way that the ServerIronXL would
know about the connection under this circumstance (duh..) At any rate does
anyone have any thoughts on this phenomenon? It has done this more than once or
twice now, and it seems to do it once every 30 days or so. If I restart named
on the effected server it seems to clear it up. I am not running src-nat
and the load balancing type is round-robin.<o:p></o:p></p>
<p class=MsoNormal style='text-indent:.5in'><o:p> </o:p></p>
<p class=MsoNormal style='text-indent:.5in'>Thanks in advance if anyone has any
thoughts ;-)<o:p></o:p></p>
