Resolution:
This is a warning message.The Max_Client_Conns option specifies the maximum number of RTclient processes that are allowed to connect to RTserver or RTgms processes. The default under SS 6.0 and greater is 200. The default under SmartSockets 5.x is 0 meaning checking for this value is disabled.

The Max_Client_Conns option specifies the maximum number of RTclient processes that are allowed to connect to RTserver. If this limit is exceeded, no more RTclients are allowed to connect. While the techniques described in File Descriptor Upper Limit in the SmartSockets User's Guide can be used to implement operating system-level brute force limit
checking, Max_Client_Conns provides a more graceful way to enforce a maximum load on RTserver. Checking for the number of RTclients is disabled if Max_Client_Conns is set to 0.
This option is required and cannot be unset.

Default: 0

What does error "TAL-SS-W Max number of client connections exceeded" mean?
