We had a similar issue which, as you have mentioned below, would occur 
"randomly" - sometimes due to firewall settings, sometimes due to active 
connection mode, and sometimes reasons that we couldnt trace.
        The workaround we applied was to set the timeout in commons-net

[jira] Created: (NET-152) FTPClient.retrieveFileStream hangs occassionally

FTPClient.retrieveFileStream hangs occassionally

                 Key: NET-152
             Project: Commons Net
          Issue Type: Bug
    Affects Versions: 1.4
         Environment: Redhat Enterprise Linux 4
            Reporter: Shashi Anand B

Occassionally, retrieveFileStream on FTPClient hangs. The thread dump 
gives the following trace: (native method) ( ( (,342) 

This seems to occur randomly. Hence, I have not been able to get any 
specific information for further debugging.  Is this a known issue? Is 
there any work-around for this issue?
