      Description

      We've observed that gfal2 sometimes encounters a communication error, and yet returns "no such file or directory", while the file does exist.
      It concerns all the SRM storage endpoints as far as I can tell.

      The error looks something like that:

      srm://srm-lhcb.gridpp.rl.ac.uk:8443/srm/managerv2?SFN=/castor/ads.rl.ac.uk/prod/lhcb/user/d/dhill/218493/218493664/LDSB.fe1jUe
      Communication error on send ( 70 : Failed to determine file size.: GError('srm-ifce err: Communication error on send, err: [SE][Ls][] httpg://srm-lhcb.gridpp.rl.ac.uk:8443/srm/managerv2: CGSI-gSOAP running on lbvobox106.cern.ch reports No such file or directory\n',
      70))
      

      However, stating the file now still works (yes yes, lcg-ls is still an easier command line to use than gfal )

      
      lcg-ls -l -D srmv2 -T srmv2 -b 'srm://srm-lhcb.gridpp.rl.ac.uk:8443/srm/managerv2?SFN=/castor/ads.rl.ac.uk/prod/lhcb/user/d/dhill/218493/218493664/LDSB.fe1jUe'

      Unfortunately, I have no way of reproducing this reliably
