[xSocket-develop] "Address already in use" errors and a question about the connection pool

[Christiaan W. <cwi...@te...>]

Hi there,

I have a client doing lots of request to a HTTP server, using about 20 
simultaneous connections. I use a while loop to create as many 
connections as possible, and if I'm at max, I'll wait until another 
connection was closed. This appears to work just fine for a while.

But then, I start getting these exceptions:

java.net.BindException: Address already in use: connect
	at sun.nio.ch.Net.connect(Native Method)
	at sun.nio.ch.SocketChannelImpl.connect(SocketChannelImpl.java:507)
	at sun.nio.ch.SocketAdaptor.connect(SocketAdaptor.java:81)
	at sun.nio.ch.SocketAdaptor.connect(SocketAdaptor.java:65)
	at org.xsocket.stream.io.impl.IoProvider.openSocket(IoProvider.java:356)
	at 
org.xsocket.stream.io.impl.IoProvider.createClientIoHandler(IoProvider.java:219)
	at org.xsocket.stream.Connection.<init>(Connection.java:162)
	at 
org.xsocket.stream.NonBlockingConnection.<init>(NonBlockingConnection.java:396)
	at 
org.xsocket.stream.NonBlockingConnection.<init>(NonBlockingConnection.java:154)

They occur in the constructor of connection NonBlockingConnection. This 
happens with 1.2 and 1.2.1

Also, this started occurring after I implemented onConnect, instead of 
sending the http POST data right after the construction of the 
NonBlockingConnection. Mostly, the second time I try to create the 
connection, it works, but this should not be happening I guess...

So, what's the problem here? It looks like someone is trying to bind a 
socket to a local tcp port that is already taken fore some reason.

Kind regards,
