There are many flaws in our current scheduling algorithm, this is one of the more serious. *** Bug 889065 has been marked as a duplicate of this bug. *** The draft of our scheduler redesign (which will fix this along with several other problems) is at http://beaker-project.org/dev/proposals/event-driven-scheduler.html The "sweeping wave" scheduling model we currently use (where all recipes are advanced through a given state change in parallel, rather than each recipe being pushed through as as many states as possible as they will be in the new design) is unfortunately fundamentally broken :( *** Bug 884683 has been marked as a duplicate of this bug. *** Beaker 0.12 has been released. |
