> Key: YUNIKORN-2030

> Project: Apache YuniKorn
> Issue Type: Bug
> Components: core - scheduler
> Reporter: Yongjun Zhang
> Assignee: Yongjun Zhang
> Priority: Major
>
> As reported in YUNIKORN-1996, we are seeing many messages like below from
> time to time:
> {code:java}
> WARN objects/application.go:1504 queue update failed unexpectedly
> {“error”: “allocation (map[memory:37580963840 pods:1 vcore:2000]) puts
> queue ‘root.test-queue’ over maximum allocation (map[memory:3300011278336
> vcore:390584]), current usage (map[memory:3291983380480 pods:91
> vcore:186000])“}{code}
> Restarting Yunikorn helps stoppinging it. Creating this Jira to investigate
> why it happened, because it's not supposed to happen as we check if there is
> enough resource headroom before calling
>
> {code:java}
> func (sa *Application) tryNode(node *Node, ask *AllocationAsk) *Allocation
> {code}
> which printed the above message, and only call it when there is enough
> headroom.
> There maybe a bug in headroom checking?
