erlang

One of gen_servers in my app call gen_tcp:listen(Port, [{active, true}]). First time I run unit test, it returns {ok, Socket}, but second time I run the same unit test, it returns an {error, eaddrinuse}, but

lsof -i TCP

returns nothing. Also, when the same unit_test is run twice on another machine (WinXP), it works as expected (that is, returns {ok, Socket} both times). Therefore, my gen_server obviously releases the port, but Erlang somehow doesn't know that.

So, how can I figure out who does Erlang think uses this address?

On one of my servers when I type netstat -n I get a huge output, something like 400 entries for httpd. The bandwidth on the server isn't high, so I'm confused as to what's causing it. I'm suspecting an attack, but not sure. Intermittently, the web server will stop responding. When this happens… >>> More
