TIME_WAIT sockets stay around for one minue or two after the request/connection has been closed. It's not normally a problem and just how TCP/IP works, but if you run a very high request rate then the server may run out of free ports due to all ports being used by TIME_WAIT sockets. First action to take is to increase the range of free ports. The default varies a lot between different OS:es and versions, from 4K to 30K. TCP/IP allows for up to 60K ports, In Linux echo 1024 65535 >/proc/sys/net/ipv4/ip_local_port_range Regards Henrik
