I don't know if this helps, but I've tried to reproduce the problem with `xrdcp` using the following: ``` xrdcp -DICPParallelChunks 1 -DICPChunkSize 4194304 root://ceph-gw8.gridpp.rl.ac.uk:1094/dteam:test1/domatest/jwalder/HTTP_1GB . ``` From #1491, I believe this should reproduce the behaviour of dCache's (current) embedded client, which makes 4 MiB read requests with a maximum of one in-flight request at any time. However, I've been _unable_ to reproduce the problem . The above command completes successfully for me. Does the `xrdcp` command "stat" the file and use the expected length to avoid downloading too many bytes? I think Andy suggested this possibility, but it would be good to know for sure. -- You are receiving this because you commented.
