I'm not sure what SYN_WAIT is, I assume you mean SYN_RECV ? A SYN_RECV
connection should go away after some time, if it doesn't it is a bug.

An ESTABLISHED connection may exists forever if no data flows, that is ok,
but others shouldn't. If you see a problem could you send me a tcpdump
log of a buggy connection establishment and/or the netstat -to output?
