      Description

      more important, I'm trying to copy dir from a dCache CMS T3 to a dCache CMS T2 by gfalFS ;
      sometimes the files copy works but then it gets stuck on a file and I see in the source dCache CMS T3 that I administer 2 file transfers for the same file like:

      GFTP-t3fs09-<unknown>-57634 t3fs09-Domain-gridftp 1414765727888 GFtp-2 2980 0 00020000000000000330BF10 t3fs02_cms 188.184.29.227 Mover t3fs02_cms/33564474: Sending 47149 RUNNING 47076 434176 9.222873651117343 47118
      GFTP-t3fs09-<unknown>-57635 t3fs09-Domain-gridftp 1414765729474 GFtp-1 2980 0 00020000000000000330BF10 t3fs02_cms 188.184.29.227 Mover t3fs02_cms/33564475: Sending 45563 QUEUED

      what I don't get is why they are 2 transfers if the file is 1 and why 1 is type GFtp-1 while the other is type GFtp-2 ; eventually gfalFS gives up for instance in this way:
