Hi, I'm experimenting with using xrdcp for the babar skiiming at RAL but some of the writes to the xrootd server fail. The only clue in the client logs I can find is: xrdcp failed with exit code 11 though there may be more being eaten by the wrappers. On the server side I see: XrdLink: Unable to receive from babar004.1969:[log in to unmask]; connection reset by peer This doesn't happen for all transfer but a significant minority fail this way. Any ideas where I should be looking for the problem? Thanks, Chris
