[jira] Commented: (DIRMINA-596) Sessions generated by
NioSocketConnector cannot be closed in time (within MINA2.0 M1,M2)
[ https://issues.apache.org/jira/browse/DIRMINA-596?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12603987#action_12603987 ]
Nathanael Van Vorst commented on DIRMINA-596:
---------------------------------------------
I see something similar. I am using a NioSocketConnector with a SslFilter. I maintain a 100 or so connections to many different servers. When I close a connected session I close it immediately (session.close()). The sessions with certain servers sometimes take a very long time to close -- seconds to even minutes. The figure this out I used the CloseFuture returned from the close() operation rather than the sessionClosed event.
Not sure if this tidbit helps......

> Key: DIRMINA-596
> URL: https://issues.apache.org/jira/browse/DIRMINA-596
> Project: MINA
> Issue Type: Bug
> Components: Core, Transport
> Affects Versions: 2.0.0-M1, 2.0.0-M2
> Environment: MINA:mina-core-2.0.0-M2-20080427.091119-1.jar
> JDK: java version "1.5.0_05"
> Plat: Windows XP
> Reporter: Silver
>
> I use MINA 2.0.0 M1 and M2 to build my application.
> When I use one NioSocketConnector to generate 10 sessions and then close them in the messageReceived event of each session, only 5 or 6 sessions(that is to say, not of all sessions) can be closed correctly, others cannot, but I can receive the sessionClosed event. The number of the closed sessions varies from 2-6 during my experiments.
> Another intersting event will occur:
> Since the rest sessions cannot be closed, I tried to generate a new session by the same NioSocketConnector, then all of the 10 "old" sessions were closed as one might expect, except the last new session.
> the main method:
> public static void main(String[] args)
> {
> NioSocketConnector acceptor = new NioSocketConnector();
> acceptor.setDefaultRemoteAddress(new InetSocketAddress("127.0.0.1", 2361));
> acceptor.getFilterChain().addLast( "executor", new ExecutorFilter(100) );
> acceptor.setHandler( new TimeServerHandler() );
> for(int i=0; i<10; i++)
> acceptor.connect();
> }
> the messageReceived method in TimeServerHandler class:
> public void messageReceived(IoSession session, Object message)
> throws Exception
> {
> System.out.println(((IoBuffer) message).getString(Charset.forName("UTF-8")
> .newDecoder()));
> session.close();
> }
