      Description

      Iwasa Kazmi reported this on server-user:


      Hi,

      I sent a message to a local user and the delivery was
      done successfully, but a FileStreamStore file is still
      in the `spool' directory.
      Is the FileStreamStore file used ?

      I'm using james-2.3.0rc1 on WinXP.

      I did the following:

      1. edit config.xml for disable server name detection.

      <servernames autodetect="false" autodetectIP="true">
      <servername>localhost</servername>
      </servernames>

      2. add user `iwasa'.

      3. send email to iwasa@localhost.

      Thank you,
      Iwasa Kazmi

      FWIW I can reproduce the issue with current 2.3rc1 and current trunk.

      Config file as default for 2.3, repositories changed to file in trunk
      (we still have derby as default in trunk).

      I connect to remote manager, create an user. Connect to smtp server and
      send a message to that user.

      The XXX.Repository.FileStreamStore file is stuck there, in the spool.
      If I restart James it got cleaned by the cleaning procedure in
      AvalonMailRepository.

      This seems to be a bug. Every file that is spooled remain there until a
      restart. This is diskspace leak.

      I tried manually calling from all the places the
      ContainerUtil.dispose(mail) and set mail to null to be sure that the
      remove were called and I can see that remove is called twice on that
      file but it is not removed. It seems that a stream is still opened when
      we try to remove it and it's not removed.

      I've not investigated more on this. I only use filerepository in a small
      production server that I rarely check. Noel, Vincenzo, can you check
      what does it happen in the long term? Maybe this is a test for
      Postage... spool folder should increase it size in a linear way if this
      bug is there.
      ------
      This could be platform specific: I'm able to reproduce it under windows.

      This would also make sense because in unix os you can remove opened
      files and they are really removed when the file is closed while under
      windows an opened file cannot be deleted.
