Description of problem: copr builds are building successfully, but the final rsync fails with an error message. Version-Release number of selected component (if applicable): How reproducible: Random, occurred twice on Fedora Rawhide, once on EPEL 7, but I only did 5 builds. Steps to Reproduce: 1. Start a copr build, possibly only on EPEL7/Fedora Rawhide 2. Wait 3. Build might be marked as failed despite rpm packages being in the fold afterwards. Actual results: Some copr builds fail inexplicably in the middle of an rsync job. Expected results: Rsync is successful Additional info: Affected builds: https://copr-be.cloud.fedoraproject.org/results/kyl191/nginx-pagespeed/fedora-rawhide-x86_64/00122195-nginx-pagespeed/build-00122195.rsync.log https://copr-be.cloud.fedoraproject.org/results/kyl191/nginx-pagespeed/epel-7-x86_64/00122218-nginx-pagespeed/build-00122218.rsync.log https://copr-be.cloud.fedoraproject.org/results/kyl191/nginx-pagespeed/fedora-rawhide-i386/00122219-nginx-pagespeed/build-00122219.rsync.log
This seems to be cause by some issues in libvirt network card driver. I followed https://www.rdoproject.org/Using_GRE_tenant_networks#Offloading and disabled offloading on frontend, backend and builders. Hopefully (as I can not reproduce it deterministic) it resolve this issue. If you ever hit it again, please reopen this BZ.
