Remko Popma commented on VFS-296:
---------------------------------
At my company we are using version 2.0 and have recently experienced our app
hanging while trying to send files over FTP. This has happened 4 times in the
previous 9 business days. We are not sure what (if anything) has changed. At
the moment we are manually recovering any time this happens. We would love to
upgrade to a version that includes this fix but 2.1 is not out yet. Is there a
plan to release 2.1 in the near future?

> Key: VFS-296
> URL: https://issues.apache.org/jira/browse/VFS-296
> Project: Commons VFS
> Issue Type: Bug
> Affects Versions: Nightly Builds
> Reporter: Andreas Persson
> Fix For: 2.1

> Attachments: sotimeout.patch, sotimeout_v2.patch

> The fix from VFS-216 doesn't help if the ftp server doesn't reply with any
> messages at all (could happen if it's behind a badly configured firewall for
> example). What happens is that the client.connect() called from
> FtpClientFactory hangs, and this line is before timeout parameter is set.
> I suggest the change in the attached patch.
> The scenario can be tested with "netcat -l" instead of a real ftp server.
