Here's the collection of logs. I also added the client-side logs (`gfal-copy` with `-vvv`) in case correlating with the client-side requests helps to pinpoint it:, and have taken the logs once with `http.tlsreuse on` and once with `http.tlsreuse on` in case of XRootD 5.0.1. For gfal, settings were always the default (i.e. session reuse on). | Setup | GFAL log | XRootD log of DTN with `-d:3` for GSI | |----------|---------------|--------------------------------------------------| | XRootD 5.0.1, `http.tlsreuse on` | [gfal-xrd5-reuse.log](https://github.com/xrootd/xrootd/files/5158670/gfal-xrd5-reuse.log) | [xrd5-reuse.log](https://github.com/xrootd/xrootd/files/5158682/xrd5-reuse.log) | | XRootD 5.0.1, `http.tlsreuse off` | [gfal-xrd5-noreuse.log](https://github.com/xrootd/xrootd/files/5158675/gfal-xrd5-noreuse.log) | [xrd5-noreuse.log](https://github.com/xrootd/xrootd/files/5158689/xrd5-noreuse.log) | | XRootD 4.12.4-0.rc2 | [gfal-xrd4.log](https://github.com/xrootd/xrootd/files/5158678/gfal-xrd4.log) | [xrd4.log](https://github.com/xrootd/xrootd/files/5158691/xrd4.log) | Let's hope something sticks out to your eyes :-). -- You are receiving this because you are subscribed to this thread.
