According to the post:
$ netstat -an | grep -c TIME_WAIT
If the count it returns keeps growing, you're seeing a slow leak. At some point, new connections will start failing. How soon depends entirely on how quickly your machine closes new connections.
Since a lot of client traffic involves the server closing connections instead, I imagine it could take a while.
It's unclear if it'll leak whenever your mac closes or only when it fails to get a (FIN, ACK) back from the peer so the TCP_WAIT garbage collector runs. If it's the latter, then it could take substantially longer, depending on connection quality.
You want to drop the wc -l.
Mac `grep -c` counts lines that match, so it always prints 1 line, so piping to wc -l will always return 1.
Or just open up and do netstat -an |grep TCP_WAIT and just watch it. If any don't disappear after a few minutes, then you're seeing the issue.
