------------------------------------

             Summary: Timeout in vsFTPd causes exception when executing another command
                 Key: VFS-567
                 URL: https://issues.apache.org/jira/browse/VFS-567
             Project: Commons VFS
          Issue Type: Bug
    Affects Versions: 2.1
         Environment: vsFTPd 3.0.2 on Kubuntu 14.10
            Reporter: Antonio Petrelli


After a timeout in vsFTPd, a QUIT command is sent and a 421 Timeout response is sent back to the Java client. After that, a SocketException (broken pipe) is raised and not correctly managed.

I am attaching a test case, this is the stack trace:
