Re: Reuse connections to avoid port starvation [Answer]

There are a bunch of sysctl kernel parameters that will aid in a speedy reuse of ports

net.ipv4.tcp_tw_recycle=1 net.ipv4.tcp_tw_reuse=1 net.ipv4.tcp_fin_timeout=20 (default is 60)

Notes about this will confuse NAT if if that plays a role in your connections.

There is a bit of discussion around this on https://stackoverflow.com/questions/410616/increasing-the-maximum-number-of-tcp-ip-connections-in-linux

Own research recommented.
