jaikiran pai commented on AS7-3402:
-----------------------------------
This is what is happening:
1) A client is doing multiple invocations (lets assume 2 invocations, in this example) to
a EJB on the server side
2) On the server side this results in 2 threads handling those 2 invocations. Thread A and
thread B.
3) Thread A ends up calling the bean method which throws an exception. The server side
attempts to write out the exception to the remote channel so that the exception is
communicated back to the client. _For some reason_ this write fails for Thread A. One
possible reason is some object in the exception instance hierarchy not being serializable.
The failure to write out this exception to the remote channel results in an IOException
and a subsequent close() on the Channel
https://github.com/jbossas/jboss-as/blob/master/ejb3/src/main/java/org/jb....
4) Now in the meantime, Thread B which too has invoked on the bean method comes back with
an exception of its own from the method invocation. The server is in the process of
writing out the exception to the channel so that its communicated back to the client. Now
since Thread A ends up closing the channel when Thread B is writing out a message to the
stream, Thread B ends up seeing "stream is closed" error.
What we need to find out is the real exception that's caused in #3 which triggers the
failure to write out the message. This will be available in the server.log.
In general, I am not sure if there's anything we can do about this, since if an
IOException occurs while writing out to the channel, the channel is expected to be closed
and writes that are currently in progress (in other threads) are bound to fail.

Key: AS7-3402
URL: https://issues.jboss.org/browse/AS7-3402
Project: Application Server 7
Issue Type: Bug
Components: EJB
Affects Versions: 7.1.0.CR1b
Reporter: Denis Pavlishin
Assignee: jaikiran pai
Priority: Blocker
Labels: ejb, jboss, xnio
Fix For: 7.1.2.Final-redhat1
Attachments: server.log
Sometimes (1 or 2 times a day) I get the following error, after which JBoss not accept
remote connections to the EJB module and my application shutdown.
