Details

(Whiteboard: [qa?])

during local load testing, I've hit a wall introduced by the default ephemeral port range in linux. Once all ephemeral ports are consumed, connect returns EADDRNOTAVAIL. Webheads do application level request forwarding, and soon will perform outbound requests to proxy servers. Client machines generate load. Both of these classes of machines should be tweaked to have the widest port range possible to support more simultaneous connections. currently on webheads the range is 30kish: $ cat /proc/sys/net/ipv4/ip_local_port_range 32768 61000 I suggest something like # echo "1024 6100" > /proc/sys/net/ipv4/ip_local_port_range

I *meant* `echo "1024 61000"`
I'd go right to 65535 as the high end.
