css 11050 web-server slb problem

[yunchouljung]

hi everyone

i have a question about css 11050

there are three web servers(1.1.1.93,96,97) and db server (1.1.1.90) in same vlan.

loadbalancing is working well.

but sometimes qeury data from webserver to db returns zero. not always.

i attach a some config file and topology

anyone who experianced this problem reply to my post ..

thanks in advance.

what kind of connections exist between web servers and db server ?

Is it permanent tcp connection ?

Or is it open - query - close ?

The problem could be the css timing out the connection.

If you know which port is being used for the db connection, try the command 'flow permanent portX XX'.

tcp connection is open-query-close

and db sevice port is 1433.
