What changes have you made? Usually the port limit is reached because of time wait sockets. If not done already try with: net.ipv4.ip_local_port_range = 1028 65535 net.ipv4.tcp_tw_reuse = 1 net.ipv4.tcp_fin_timeout = 30 Increasing the ephemeral port range (usually by default it starts around 30k so you effectively lose 30k ports - obviously adjust the lower limit to your application needs). Then time wait socket reuse helps a lot and also decreasing the FIN timeout (the default is something like 60 seconds). rr _______________________________________________ nginx mailing list nginx@nginx.org http://mailman.nginx.org/mailman/listinfo/nginx
