Hi, Since it works with v5.4.3 I think/thought that rules out a problem with the zip file. $ zip -T RAW.21051586._000001.zip.1 test of RAW.21051586._000001.zip.1 OK I don`t see a useful difference in the log. The offset and size are the same, but the open fails [0x23a7250@file://localhost/tmp/walkerr/RAW.21051586._000001.zip.1?xrdcl.requuid=4da9d0dc-4474-4d8f-8ff7-97c4126c7159&xrdcl.unzip=data15_13TeV.00266904.debugrec_hlt.merge.RAW.g17._0001.1] Got state response for message kXR_read (handle: 0x09000000, offset: 11824956046, size: 1050) [0x23a70e0] CD records parsed.

The total file size is a little different $ ls -l /tmp/RAW.21051586._000001.zip.1 /tmp/RAW.21051586._000001.zip.zero -rw-r--r--. 1 walkerr zp 11824957194 10. Jan 17:40 /tmp/RAW.21051586._000001.zip.1 -rw-r--r--. 1 walkerr zp 11824957466 11. Jan 10:40 /tmp/RAW.21051586._000001.zip.zero but the 'unzip -v' output is identical. They should be readable on lxplus737 for a while. To summarise, there maybe something odd with the zip file, but it works in zip/unzip and older xrdcp version.
