This is really a networking problem in my opinion, but our techs are trying to blame it on the CF servers, so I'll give you guys a try.
After moving all our web servers over to the same firewall, we noticed an awful lot of TCP sessions all between the load balancer (hardware) and our users going through that firewall. We have about 8 different web servers all behind the load balancer clustered into three main sites. Our usage is high, but since it is an internal app, we only have about 200 - 300 users. Our firewall allows for a maximum of 64,000 "sessions", which I assume equates to open TCP connections. We regularly max that number out; and according to our log files we may only have 100 users at one time, but they will have thousands of sessions for each user (up to 9,000). Unfortunately all the network guys that actually know anything about our network quit recently, and the remaining guy (who had never heard of "netstat") thinks our ColdFusion code "is doing something" to consume too many sessions. Of course, this same guy doesn't understand the difference between a CF "session" and a firewall "session". He thinks his TCP sessions expire when he is logged out of our site. Our load balancer uses sticky sessions and I think the sticky age is set to 60 minutes. Is that making the load balancer keep EVERY TCP session open for an hour-including EVERY image, every js file, and CSS, file etc?? I'm kind of in over my head here, but nobody else around here knows anything useful. Our load balancer is a Foundry ServerIron. Our Firewall is a Juniper SSG-520. Are our servers configured wrong, or is our firewall underpowered? ~Brad ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~| Check out the new features and enhancements in the latest product release - download the "What's New PDF" now http://download.macromedia.com/pub/labs/coldfusion/cf8_beta_whatsnew_052907.pdf Archive: http://www.houseoffusion.com/groups/CF-Talk/message.cfm/messageid:294233 Subscription: http://www.houseoffusion.com/groups/CF-Talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=89.70.4
