From time to time I getan error like this on CI:

FAILED test/test_base.py::TestBase::test_with_rw_remote_and_rw_repo - git.exc.GitCommandError: Cmd('git') failed due to: exit code(128)  cmdline: git ls-remote daemon_origin  stderr: 'fatal: unable to connect to localhost:localhost[0: ::1]: errno=Connection refusedlocalhost[1: 127.0.0.1]: errno=Connection refused'

I'm not sure why this happens, but I see it every few days or so, on days I'm pushing lots of commits (more precisely: on days I rungit push many times, since CI is only running on the tip of the pushed branch). It happens both in my fork, in PRs here on this upstream repository (as in#1675 detailed above), and in pushes to this upstream repository (as ind1c1f31). Rerunning the CI check gets rid of it; that is, it doesn't recur. I don't think I've had this locally, but I don't run the tests locally as much as on CI.

Searching reveals that something like this, perhaps the exact thing, happened in#1119, so thismay be known. I'm not sure if its known still to be occasionally occurring, or if there is anything that can reasonably be done to make it happen even less often or not at all. (If it's not worth having an issue on this, then I don't mind this simply being closed.)
