All the CiviCRM tests seem to be failing in CI lately, with mysterious DB errors.
E.g. https://integration.wikimedia.org/ci/job/wikimedia-fundraising-civicrm/7367/console, https://integration.wikimedia.org/ci/job/wikimedia-fundraising-civicrm/7359/console.
Are there new limits on RAM or query timeouts for CI databases?
