Connection Limit

You can use the set_availability method to stop all future connections from being routed to that node.

void ITCMLocalLB::Node::set_availability( 
     in IPPortDefinition[] node_defs, 
     in AvailabilityState state 
 );

Keep in mind that any new connections from a client that had a previous connection to the node you made unavailable will be treated as a new connection and routed away from that node.
