If system time is adjusted first forward and then backward while a masakari-engine service is running, then the periodic tasks stops for the duration of time the system clock was adjusted backward. This was supposed to be fixed by the following patch to oslo.service https://review.openstack.org/#/c/286838/ , but the order of imports in unit tests and production code is different, so masakari services end up starting with the default eventlet hub, that does not use a monotonic clock and, thus, is affected by changes of system time. Testing the change done in the patch is problematic, as it's a subject of imports order and is not reproduced in functional or unit tests (oslo_service is always imported earlier than eventlet hub is initialized, so it just does "the right thing"). The alternative is to make an assertion when services start. Co-Authored-By: Roman Podoliaka <rpodolyaka@mirantis.com> Closes-Bug: #1510234 Change-Id: I9d917b3151d9cdf7340a173b5baf98def63c76cd
