await() forever
---------------
Key: DIRMINA-792
URL: https://issues.apache.org/jira/browse/DIRMINA-792
Project: MINA
Issue Type: Bug
Components: Core
Affects Versions: 2.0.0-RC1
Environment: java 6, Windows XP, 32 Bit
Reporter: Haug Bürger
After some time of operation the following code waits forever.
WriteFuture wf = getSession().write(message);
wf.await();
I have an application that successfully sends between 20-200 messages before
running into the await() forever situation. What I saw with a network sniffer
is that the TCP-ACK for the message has send by the receiving application.
Since we have the same situation with multiple configurations, over company
LAN, direct ethernet connection and both applications on the same machine I
think it is not a network problem. What we saw at the log is that the TCP-ACK
took more than 150ms before the call blocks.
I replaced the await code with wf.await(100L) which comes back but
wf.isWritten() is still false. I'm not sure about the consequences of not
waiting for the data to be written to the TCP-stack. Is this what await() does?
I tried to find the connection between the real write operation and the future
but gave up. I could not even log the queue size or any other debug
information. If somebody knows which of the accessible values makes sense to
log or how to reschedule the read request, add a comment.
