<p class=MsoNormal>Do you mind to share your config? Have you checked what is
happening using a sniffer at the real server or via debug filter at the
ServerIron?<br>

<span style='font-size:10.0pt'>Hi,<br>
We've been running ServerIronXL hardware for a few years and I've just
purchased some new chassis based replacements with WSM modules.<br>
<br>
I've been porting our existing load balanced services over to the new boxes and
have come across a funny.<br>
<br>
I provide a server load balanced DNS service via our foundry kit. and have 3
"remote" servers defined and bound to a VIP. I've configured the serveriron
to perform a zone health check and on each of the 3 servers I can see the
health check coming in. The same real servers are also used by our XL
boxes in the interim.<br>
<br>
What I've found is that weven though the serveriron thinks all 3 servers are active,
when it tries to use the last one in the group of remote servers the query
never reaches the server. a sh server real doesn't show any connections to the
server. From the users point of view the query never resolves. If i take down
the dns server on the remote server so that the serveriron health check fails,
it succesfully uses the other two servers and everything is o.k.<br>
<br>
I've switched off iptables on my real(remote) servers but it doesn't make any
difference. As far as i can see all my servers are identical. I have the same
setup on another serverion on our west campus with anoter 3 servers and it does
the same thing.<br>
<br>
Anyone else seen this?<br>
<br>
TIA<br>
Alex</span> <br>
