Hi Wei,

I've just tried to copy a number of files with xrdcp in a loop. It 
worked fine for 15 files and
then I started to get I/O errors (see below).

bash-4.1$ for i in `seq 136 199`;do xrdcp -f 
root://dtn04.nersc.gov//atlas/rucio/mc16_13TeV:EVNT.13836203._000${i}.pool.root.1 
EVNT.13836203._000${i}.pool.root.1;done
