TCPView (Windows only) from Windows Sysinternals is my favorite app whenever I have a JVM_BIND error. It shows which processes are listening on which port. It also provides a convenient context menu to either kill the process or close the connection that is getting in the way. share|improve this answer edited Oct 30 '13 at 17:34 informatik01 9,24763759 answered Oct 5 '12 at 0:13 Guido Simone 5,7241814 1 Thank You Very Much , TcpView is A+ –Coffee Oct 5 '12 at 1:25 a quick work around: Open server view > double click on the server > change the port numbers used (ie. for Tomcat admin, HTTP/1.1, & AJP/1.3) –Adrien Be Sep 27 '13 at 7:01 TCPView worked for me thx a lot :) –Chris Sim Mar 21 at 10:55 add a comment| up vote 73 down vote If you know what port the process is running you can type: lsof -i:
and both ends must ACK (acknowledge) each other's FIN packets. The FIN packets are initiated by the application performing a close(), a shutdown(), or an exit(). The ACKs are handled by the

kernel after the close() has completed. Because of this, it is possible for the address already in use bind c process to complete before the kernel has released the associated network resource, and this port cannot be bound to another process until bind failed address already in use iperf the kernel has decided that it is done. Figure 1 Figure 1 shows all of the possible states that can occur during a normal closure, depending on the order in which things happen. Note that if you http://stackoverflow.com/questions/12737293/how-do-i-resolve-the-java-net-bindexception-address-already-in-use-jvm-bind initiate closure, there is a TIME_WAIT state that is absent from the other side. This TIME_WAIT is necessary in case the ACK you sent wasn't received, or in case spurious packets show up for other reasons. I'm really not sure why this state isn't necessary on the other side, when the remote end initiates closure, but this is definitely the case. TIME_WAIT is the state that typically ties up the port for several http://hea-www.harvard.edu/~fine/Tech/addrinuse.html minutes after the process has completed. The length of the associated timeout varies on different operating systems, and may be dynamic on some operating systems, however typical values are in the range of one to four minutes. If both ends send a FIN before either end receives it, both ends will have to go through TIME_WAIT. Normal Closure of Listen Sockets A socket which is listening for connections can be closed immediately if there are no connections pending, and the state proceeds directly to CLOSED. If connections are pending however, FIN_WAIT_1 is entered, and a TIME_WAIT is inevitable. Note that it is impossible to completely guarantee a clean closure here. While you can check the connections using a select() call before closure, a tiny but real possibility exists that a connection could arrive after the select() but before the close(). Abnormal Closure If the remote application dies unexpectedly while the connection is established, the local end will have to initiate closure. In this case TIME_WAIT is unavoidable. If the remote end disappears due to a network failure, or the remote machine reboots (both are rare), the local port will be tied up until each state times out. Worse, some older operating systems do not implement a timeout for FIN_WAIT_2, and it is possible to get stuck ther

"bind: Address already in use" Dear friends, I'm very new to Ubuntu and not very firm with the terminal syntax and system settings yet. I hope someone can advice me on two issues regarding SSH and the secure use of scripts in the terminal. So yesterday I sucessfully set up a ssh tunnel with PuTTY SSH Client defining Source Pourt and Destination under -> SSH ->Tunnels. And today I tried to do the same but using the build-in SSH client in the terminal. I entered the following syntax: ssh -f -L 5432:localhost:5433 someAccountname@someIPaddress sleep 10 I was prompted to enter a password. After entering the password the following error message appeared: "bind: Address already in use" So I guessed that PuTTY was still using the local port. After deinstalling PuTTY the same errormessage came up and after reinstalling PuTTY all configuration was still there. So I guess that PuTTY somehow changes a c
// ln is listening on :8080 err = ln.Close() // succeeds, no error if err != nil { log.Fatal(err) } ln2, err := net.Listen("tcp", ":8080") if err != nil { log.Fatal(err) // bind: address already in use } I was wondering if SO_REUSEADDR had something to do with this, but as far as I know, that is already being used under the hood in the Go standard library when creating a new tcp listener. Any ideas how I can re-bind to that address without delay? jdh (Joe Henke) 2015-11-14 18:40:19 UTC #2 Hey Matt, I tried to reproduce this and did not on my mac but did on the go playground. Where did this happen for you? Interestingly, both on my mac and on the go playground, if you use -addr="" or change to defaultAddr to "" in the source (which I think just means it will bind to any open port, yeah?) it will never rebind to the same port, and in fact will bind to the previous attempt's port + 1. Not sure if this is significant; I don't know precisely what binding to "" is specced to do. Joe matt (Matt Holt) 2015-11-14 19:09:42 UTC #3 Thanks for trying to reproduce it - next time I'll try to provide a full code sample I'm experiencing the Go playground's behavior on my Mac. But when I ran your test program on my Mac, it passed. I will look into this further in my own program. Meanwhile, I am intensely curious as to why the test fails on the Go playground... matt (Matt Holt) 2015-11-14 19:57:23 UTC #4 Okay, I've narrowed it down a little bit. This only happens for me when my program has restarted itself using exec.Command(os.Args[0], ...) and, in that command, it sets ExtraFiles to a list of file descriptors for listeners. (Similar to this method: http://grisha.org/blog/2014/06/03/graceful-restart-in-golang/) This lets the child process (itself) use the existing listeners without downtime. In the "restarted" process, then: I close the listeners, immediately create new ones on the same addresses again, and it fails with "address already in use". But if I pause 5 seconds after closing the listener (before creating the new listener), it succeeds. The original process where the listeners were created don't have this problem. In other words, if I don't "restart" the process, I can close and create the listeners immediately, like @jdh's program does. But if I do that same thing in a restart, it doesn't work. Here's a program that reproduces what I'm describing: gist.github.com https://gist.gi
