[Swift-user] Re: 3rd party transfers

I have seen GridFTP do that under high load. That is why throttles are
in place for transfers.

What I would do to confirm that the problem is with the server (which is
my suspicion, since the complaint is about a server file) is to try to
reproduce the problem with plain gridftp, but that may require writing
some C code.

Before that, however, I would make some traces of all the mlst commands
issues and double checked if the parameters don't somehow get messed up.
