I'm losing connections via the FTP task in Ant. I'm running Ant 1.7.1 in
Eclipse 3.5.1 (Galileo). I am running the Ant script directly from
within Eclipse, not from the command line. commons-net-2.0 and
jakarta-oro-2.0.8 are both visible to the FTP tasks.

I am trying to access my personal webspace provided by my ISP. I can
access it via WinSCP (4.1.8) but the Ant FTP task keeps losing the
connection.

I have several FTP tasks doing a variety of file-deletes,
directory-deletes, directory-creates and uploads, all within a single
target. Unfortunately, the target stalls out at different places every
time I run it.

Here is a typical upload:

  <echo message="Populating Foo directory."/>
  <ftp action="send" server="${ISP.hostname}" userid="${userid}"
password="${password}"
    description="Populate Foo directory"
    remotedir="${ISP.Foo.dir}/word"
    retriesallowed="${retries.allowed}"
    separator="/" binary="no" verbose="yes">
    <fileset dir="${foo.dir}">
       <patternset refid="ps.foo"/>
       </fileset>
    </ftp>

By the way, "retries.allowed" has a value of -1, allowing for unlimited
retries.


Here is the stacktrace from my latest attempt:

Does anyone have any idea why I'm getting these resets and what I can do
to prevent them?
