We set up 4 xrootd servers (version 3.2.6), and are having a trouble to write files via redirectors. 

Below is the full log (debug level 2) of writing test from a local machine, and it ends up with 'Unable to access file; file does not exist.', while direct write attempt succeeds (via port 1095). 

In the middle of the log, I see 'Unable to access file; file does not exist.(error code: 3011)'.. but no idea why this happen. 

Strange thing is.. if there's an existing file with a same name, then file copy via redirector also succeeds.. See below trials. 

Can somebody give me an advise? 

Best regards,

WooJin.
