Hi Daniel,

Oh I missed the reply for some reason. Thank you very much for both replying and reminding :) We do want to receive the replies so closing the connection isn't an option. Listening on multiple tcp ports sound like a good temporary solution, but lack of scalability?

Regards,

Allen

Hello,

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
