Join them; it only takes a minute: Sign up “java.net.BindException: Address already java.net.bindexception: address already in use linux in use” when trying to do rapid Socket creation and destruction for load testing up vote 14 down vote favorite 4 I'm trying to load test a Java server by opening a large number of socket connections to the server, authenticating, closing the connection, then repeating. My app runs great for awhile but eventually I get: java.net.BindException: Address already in use: connect According to documentation java.net.bindexception address already in use bind jetty I read, the reason for this is that closed sockets still occupy the local address assigned to them for a period of time after close() was called. This is OS dependent but can be on the order of minutes. I tried calling setReuseAddress(true) on the socket with the hopes that its address would be reusable immediately after close() was called. Unfortunately this doesn't seem to be the case. My code for socket creation is: Socket socket = new Socket(); socket.setReuseAddress(true); socket.connect(new InetSocketAddress(m_host, m_port)); But I still get this error: java.net.BindException: Address already in use: connect after awhile. Is there any other way to accomplish what I'm trying to do? I would like to for instance: open 100 sockets, close them all, open 200 sockets, close them all, open 300, etc. up to a max of 2000 or so sockets. Any help would be greatly appreciated! java sockets networking tcp share|improve this question edited Feb 19 '12 at 8:30 this.lau_ 39k30142252 asked Jan 16 '11 at 22:53 Ones3k2 1681214 1 Is it the server or the client that throws the exception? Does it happen after a consistent number of connections? –Cameron Skinn

I have two computers running the same app. With one I get the above exception. The other runs fine. The app hits a Mysql db with a lot of updates. The break occurs at diffferent places in my code depending on what updates I run. The computer that works is running windows 2000. The one that breaks is running XP pro. Other than that the configurations are as identical as I can make them.
