If you SO_REUSEADDR before on win32, you will share any existing port that's previously opened by any other application.

Re: Using APR with tomcat leaves port 8009 bound when tomcat is terminated?
D'OH!!! Why doesn't this become an apr_sockattr element to the apr_socket_create or apr_socket_bind call, so that APR determines the before/after thingy? One side note, you setopt *after* the bind if you want to know you are the absolute owner of the socket. you setopt *before* the bind on win32 if you know your app owns the socket and now you want to add additional listeners (processes) to pay attention to it. Dunno how we could map this all that cleanly. Bill William A.

Remy or anyone else working on the native connector, I'm not the only one who has seen this problem and obviously the Java code isn't doing what you expected. Any chance you of this patch getting accepted now? If not, would you be able to explain why not? Thanks in advance. , Josh. -Original Message- From: Sean Neeley [mailto:[EMAIL PROTECTED] Sent: Wednesday, February 22, 2006 10:59 AM To: Tomcat Users List Subject: RE: Using APR with tomcat leaves port 8009 bound when tomcat is terminated? I built the native connector myself. The platform is Red Hat linux 8.0, kernel 2.4.32. Many, many thanks for the patch. The socket option used in the patch is also what the APR team recommended. I hope someone adds this change permanently in the tomcat source. - Sean -Original Message- From: Fenlason, Josh [mailto:[EMAIL PROTECTED] Sent: Wednesday, February 22, 2006 10:35 AM To: Tomcat Users List Subject: RE: Using APR with tomcat leaves port 8009 bound when tomcat is terminated? I had the same problem and submitted a patch (with help from Bill Barker). The patch is below and I attached the thread Bill and I had to come to it in case your curious. You'll have to rebuild the native connector, but this should solve your problem. What platform are you on? Did you build the native connector yourself? Or where did you get the binary from?

Hi, I'm using APR 1.2.2 with Tomcat 5.5.15. Occasionally I need to restart the JVM, and so I have one of my servlets call System.exit(0). When using the APR libraries with tomcat, exiting the JVM in this manor leaves port 8009 in the FIN_WAIT2 state (see netstat man page). This prevents me from starting tomcat back up immediately. I receive an error saying that the tomcat port is already bound. If I remove the APR libraries so that tomcat does not use them, I no longer encounter this problem. Can someone help? I would like to use APR, but this problem prevents me. I have already posted this issue to the APR mailing list, and they say that the problem is with tomcat. Thanks. - Sean - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
