Collect CI logs flaky test

[agoscinski]

This an issue to collect the logs of the CI runs that fail inconsistently. Please commit the raw log (download by Download log archive) of the failed tests to the branch flaky-tests-logs. Create a new folder with the full commit hash and reference the PR and the short commit hash in the commit message. Also if possible put here a snippet of the error message here together with the commit hash on the branch flaky-tests-logs. We do it so complicated as GitHub expires files when uploaded in the issue directly.

There is already this issue #4281 but since there are no logs of the runs, and the CI runs are already expired, and the line numbers are also not up to date. It is a bit hard to continue from this discussion.

On PR #6847 tests/restapi/test_statistics.py failed many times, with no apparent reason.
We ignored and after a week passed.
There's no connection between the commits that was merged in the meantime. Therefore I'd mark as flaky.
(Also in the passed the very same test was failing on a different PR, which by re-running passed successfully.)
