The full test results are available in `/build/irmin-2.2.0/_build/default/_build/_tests/B63F4837-A612-47CB-A757-649488EDDE36`.
2 errors! in 33.000s. 52 tests run.

Also ran dune runtest -p irmin-http in a nix-shell -A irmin-http a few times and it gave inconsistent results even outside of the sandbox its built in usually (which I first suspected was the issue).

I’ve observed this kind of failures on busy machines. Might be worth to report it upstream.

I marked this as stale due to inactivity. → More info

Has been resolved in the meantime, forgot to close :)
