Version: 4.6.1-1

This is likely caused by two concurrent processes which are xrdcp to a destination path which does not exist. The first one does the mkdir to create the destination path and the other one tries to do the same but fails because the path in the meantime was already created by the first one.

Example:

2017-08-18 17:04:48,062 BackupThread env XRD_LOGLEVEL=Error XrdSecPROTOCOL=sss xrdcp --nopbar --verbose --force --retry 3 --tpc only root://localhost.localdomain//eos/?eos.lfn=fid:564441388&eos.ruid=2&eos.rgid=2 root://eosbackup.cern.ch//eos/backup/instance/user/data/170818/0000dc7c/564441388?eos.ruid=eosarchi&eos.rgid=c3&eos.app=backup_daily
