AprEndpoint$Acceptor blocking on accept.

[beve]

Hi,

We are having a problem with Apache APR with JBossESB (http://jira.jboss.com/jira/browse/JBESB-1378).

The problem we have is that we need to be able to redeploy our services but the port we are using is still in-use when we deploy the service again.

I've added some log statements and can see that AprEndPoint.destroy is getting called, but if I run netstat I can see that the port is still in-use.
Telneting to the port will "free" the port.

I seems like AprEndPoint$Acceptor.run is blocking on the call to :

 getWorkerThread().assign(Socket.accept(serverSock), true);

I noticed the following comment in the run method of

// The processor will recycle itself when it finishes

This seems to indicate that there is a way to recycle
the Acceptor and maybe break out of the accept method.
Or is there a way to make the Socket.accept method non-blocking or have a timeout perhaps?

Or is there something obvious that we are missing that could be configured.

Any suggestions are welcome!

Thanks,

Daniel

I've learnt that the Apr connector has a unlockAccept
method that should break the accept call by
making a dummy request to 127.0.0.1"

But I can't get this to work unless I write something to the socket like this:

protected void unlockAccept() {
 java.net.Socket s = null;
 try {
 // Need to create a connection to unlock the accept();
 if (address == null) {
 s = new java.net.Socket("127.0.0.1", port);
 } else {
 s = new java.net.Socket(address, port);
 // setting soLinger to a small value will help shutdown the
 // connection quicker
 s.setSoLinger(true, 0);
 } 
 s.getOutputStream().write("dummyStr".getBytes());
 } catch(Exception e) {
...
}

Is anyone else seeing this behaviour

Thanks,

Daniel
