If you are using a TCP transport channel, you can add the following custom property to the configuration settings for that channel.
Following is a description of the TCP custom property that WebSphere Application Server provides. This property is not shown on the settings page for a TCP transport channel.
This property is only valid for the i5/OS and distributed platforms. Use the listenBacklog property to specify the maximum number of outstanding connect requests that the operating system will buffer while it waits for the application server to accept the connections. If a client attempts to connect when this operating system buffer is full, the connect request will be rejected. Set this value to the number of concurrent connections that you would like to allow. Keep in mind that a single client browser might need to open multiple concurrent connections (perhaps 4 or 5); however, also keep in mind that increasing this value consumes more kernel resources. The value of this property is specific to each transport.
