CXF hangs after many transactions on one client proxy using MTOM
----------------------------------------------------------------

                 Key: CXF-3259
                 URL: https://issues.apache.org/jira/browse/CXF-3259
             Project: CXF
          Issue Type: Bug
          Components: JAX-WS Runtime
    Affects Versions: 2.3.1
         Environment: All Linux/OSX
            Reporter: Ian Helmke


CXF is hanging and timing out with a java.net.SocketTimeoutException after we attempt a number of transactions. The exact number of transactions that go through successfully before we get the exception varies widely; I have seen as few as 200 run successfully or as many as several thousand. It consistently does eventually fail and throw an exception, however. We are using MTOM.

A git repository with sample code and a junit test case that fairly reliably reproduces this problem can be found at: https://github.com/basis-technology-corp/cxf-connection-timeout

The stacktrace is as follows:
