Daniel Bevenius commented on JBESB-1378:
----------------------------------------

I've verified that this issue occurs when using Apache APR on Linux.

The problem seems to be that org.apache.tomcat.util.net.AprEndpoint$Acceptor's run method is blocking on accept:
public void run() {
            log.info( "Aceptor.run...");
            // Loop until we receive a shutdown command
            while (running) {

                // Loop if endpoint is paused
                while (paused) {
                    try {
                        Thread.sleep(1000);
                    } catch (InterruptedException e) {
                        // Ignore
                    }
                }

                try {
                    // Allocate a new worker thread
                    // Accept the next incoming connection from the server socket
                    // Hand this socket off to an appropriate processor
		    log.info( "Aceptor.run.accept serverSock : " + serverSock + ", port : " + port);
                    getWorkerThread().assign(Socket.accept(serverSock), true);
                } catch (Throwable t) {
                    log.error(sm.getString("endpoint.accept.fail"), t);
                }

                // The processor will recycle itself when it finishes

            }
            log.info( "Aceptor.run...done");
}

After 'ant-undeploy' the following netstat call produces:
#netstat -na | grep 8765
tcp        0      0 127.0.0.1:8765          0.0.0.0:*               LISTEN

Now, telneting like this:
telnet localhost 8765
will exit the accept block and the check "if (running) will make the method exit, and the quickstart can be redeployed as the port is now free.

I'll post to the jbossweb forum and see if they can help us out. There might be a way to make the accept call no-blocking or there might be a way to force the method to exit which might be what "The processor will recycle itself when it finishes" is indicating.  I've been trying to play around with various settings for the AprEndpoint class but without success.
