> Key: OODT-659
> URL: https://issues.apache.org/jira/browse/OODT-659
> Project: OODT
> Issue Type: Bug
> Components: push pull framework
> Affects Versions: 0.6
> Environment: *nix
> Reporter: Cameron Goodale
> Assignee: Cameron Goodale
> Fix For: 0.7
>
>
> While trying to download files from an FTP server with 6400+ files on it
> pushpull would crash with a 421 Error from the FTP server.
> After a lot of research and testing we found that the code was calling pwd()
> for each file when building up the list within the ls() method.
> In the case of trying to scan a directory with a large number of files, this
> can make the FTP server drop the connection due to the large number of
> request.
> We moved the call to pwd outside of the loop, and everything works great. We
> are able to download the files easily now.
