Hi list, I have a loadbalancer before sipproxies. I call t_reley() on the dispatcher to forward requests to destinations. All goes well under low load. But when load goes up to 500 requests/s, the loadbalancer still sends requests via only one tcp connection. This maxes out the tcp write queue. Of course I can increase the 'tcp_conn_wq_max' value but it doesn't solve the root problem. How do I make the loadbalancer start a new tcp connection to the destination when existing one becomes too busy? (Is it possible?) Regards, Allen
