> Project: Ambari
> Issue Type: Bug

> Affects Versions: 2.1.2
> Reporter: Aravindan Vijayan
> Assignee: Aravindan Vijayan
> Priority: Critical
> Fix For: 2.1.3

>
> Problem
> On the Ambari dashboard page, when different time ranges are randomly chosen,
> the metrics charts stop responding and an OutOfMemory is seen in the Ambari
> server logs.
> Bug
> In the AMS cache layer, the logic to update the cache entry map by removing
> values outside the given requested time range eventually leads to memory leak.
> Fix
> Change the logic to explicitly by using the iterator.remove() to remove the
> entries instead of using the map.clear() method.
