CSS11506 Quits passing traffic for 21 seconds.

[allen.external]

I am doing HTTP loadbalancing with 2 servers and 2 CSSs. When we loose one http server the CSS stops accecpting new http connections for 21 seconds. Existing connections move over to the other sever just find and continue the session without a problem. It is only new sessions that are droped. I have set my keep alives on the services to 2/2/2. It does not make a differnence what times I set keep alives too. I have also moved the clinet to the same network as the servers just for the heck of it and I get the same result. If I loose a CSS all connections move to the backup CSS just fine. It is only when we loose a service/server do we see the loss of new connections. Sniffer traces show that the CSS gets the tcp syn but it never passes it on the the web servers for 21 seconds. Any Ideas guys?

Thanks

Maybe this will help. I changed my keepalives to http. If we shut down IIS on the web sever. Everything works just fine and it does a fail over in a few seconds. So it looks to be only when we loose physical connection with the server does the CSS quit establishing new connections for 21 seconds.

Hi,

is this problem already solved? If not, could you please post the other www-services and the config of the content rule so that we can get an imagination of what is configured. Next please tell us which version you are using.

Kind regards,

Joerg
