Removed nova and oslo-incubator because the only change was in oslo.service:
https://review.openstack.org/#/c/190372/ And the fix has been here since 0.1.0. Nova 12.0.0 requires oslo.service>=0.7.0 so you should have the fix: https://github.com/openstack/nova/blob/12.0.0/requirements.txt#L48 If it doesn't fix it, I'd open a new bug and refer to this one along with the details / recreate scenario / logs of what you're seeing. ** No longer affects: oslo-incubator ** No longer affects: nova -- You received this bug notification because you are a member of Yahoo! Engineering Team, which is subscribed to OpenStack Compute (nova). https://bugs.launchpad.net/bugs/1450438 Title: loopingcall: if a time drift to the future occurs, all timers will be blocked Status in oslo.service: Fix Released Bug description: Due to the fact that loopingcall.py uses time.time for recording wall- clock time which is not guaranteed to be monotonic, if a time drift to the future occurs, and then gets corrected, all the timers will get blocked until the actual time reaches the moment of the original drift. This can be pretty bad if the interval is not insignificant - in Nova's case - all services uses FixedIntervalLoopingCall for it's heartbeat periodic tasks - if a drift is on the order of magnitude of several hours, no heartbeats will happen. DynamicLoopingCall is affected by this as well but because it relies on eventlet which would also use a non-monotonic time.time function for it's internal timers. Solving this will require looping calls to start using a monotonic timer (for python 2.7 there is a monotonic package). Also all services that want to use timers and avoid this issue should doe something like import monotonic hub = eventlet.get_hub() hub.clock = monotonic.monotonic immediately after calling eventlet.monkey_patch() To manage notifications about this bug go to: https://bugs.launchpad.net/oslo.service/+bug/1450438/+subscriptions -- Mailing list: https://launchpad.net/~yahoo-eng-team Post to : [email protected] Unsubscribe : https://launchpad.net/~yahoo-eng-team More help : https://help.launchpad.net/ListHelp
