Hello,
I have a pair of hosts. One of them performs a massive amount of
TCP connections to the other one, all to the same port. This setup
mostly works fine, but from time to time (that varies, from once a
minute to one a half an hour), the connect(2) syscall fails with EADDRINUSE. The connection rate tops to 50 connection
so, what does netstat -aAn show?

How can I get any usable information from netstat? It shows a bunch of
connections, of course, but since connect(2) failed, I have no idea what
local port I was trying to use.
but you can get an idea of the local socket distribution, and what state all
the sockets are in (TIME_WAIT etc).


And, what I forgot to mention, it's a SMP box, which could matter in
case of some race condition.

hopefully not.

  • Re: FreeBSD 7.0: sockets stuck in CLOSED state...
    ... In FreeBSD, as with all UNIX/Berkeley sockets systems, each socket is actually represented by a set of data structures representing different layers of abstraction. ... For example, if you close the file descriptor, freeing struct file, the socket and protocol state may persist for some time until the TCP connection closes. ... one is that TCP connections now appear in netstat in the CLOSED state for longer than before, and another is that open sockets that are associated with CLOSED TCP connections now count against the global resource limit on the number of simultaneous TCP connections. ...
