<div>That's because you have the default load-balacing predictor as least-connection ( you wont see in the config, because this is default).</div> <div> </div> <div>dns connections are usually short-lived, connections get closed pretty fast. First connections goes to DNS2. by the time second connections comes, there are no existing connections on any of the 2 servers, so Foundry decided to forward the request to DNS2 because of least-connection predictor. least connections looks at currently how many total number of connections are handled by any server </div> <div> </div> <div>Now, configure "server predictor round-robin", you are at peace and see both servers taking equal number of connections. round-robin is dumb, first connection go to DNS1, next time go to DNS2, third request take it to DNS1, and fourth one goes to DNS2. </div> <div> </div> <div>Foundry is coming out with powerful ServerIron 4G(read 4 Gig ports) with SSL support,
better upgrade to that, its pretty cheap.</div> <div> </div> <div>-Ramesh</div> <div> </div> <div>Hope <BR><B><I>Tom Samplonius <tom@uniserve.com></I></B> wrote:</div> <BLOCKQUOTE class=replbq style="PADDING-LEFT: 5px; MARGIN-LEFT: 5px; BORDER-LEFT: #1010ff 2px solid"><BR>DNS2 might be too slow to respond, or lost a few hundred requests.<BR><BR>From reading the docs, the SI has special handling for DNS requests.
