ok why does the erlang VM run `bind()` all the time for no apparent reason?
this is what i am trying to use to diagnose the erlang networking mystery:https://gist.github.com/jvns/c7e277c7a44e22ce5a6e5707febcfbf3 …

@b0rk curious what makes you think it's making external connections? all I really see is it trying to bind on 0.0.0.0 and failing. -
@b0rk oh so you mean it's supposed to be making outgoing connections? -
@Ryan_Jarv yeah! - Show more

@b0rk 2000 connections per sec is a fascination magic number. Wait states after connection close clogging the pool?#thinkingoutloud -
@feonixrift@b0rk good thought... Maybe netstat output would be helpful? I've seen massive wait states on Linux but not w/ pegged cpu. -
-
@feonixrift@b0rk oooh, makes sense. Thanks!
-
-
@b0rk how do you start it? -
-
@b0rk probably be a long shot, may check out epmd stuff... http://erlang.org/doc/man/epmd.html … -
@b0rk can't say that isolating erlang network issues is on my skills list, though... ;-) -
@b0rk epmd runs alongside the erlang apps, though... ruling it out may at least isolate the network issue to the app itself
-
-
@b0rk Have you already run netstat to see if you ran out of ephemeral ports? -
@b0rk Getting EADDRINUSE from the bind() suggests that it may be running out of ports in the ephemeral port range. Not sure why, though. -
@b0rk what does netstat -t say? You may be running out of ports for outgoing conns
