----------------------------------
Priority: Critical (was: Major)
> Ozone recon server possible memory leak
> ---------------------------------------
>
> Key: HDDS-7500
> URL: https://issues.apache.org/jira/browse/HDDS-7500
> Project: Apache Ozone
> Issue Type: Bug
> Components: Ozone Recon
> Reporter: George Huang
> Assignee: Devesh Kumar Singh
> Priority: Critical
> Labels: pull-request-available
> Fix For: 1.4.0
>
>
> This seems to be an issue in Recon and needs fix after analysing the OM rocks
> DB. In Recon, we are running a namespacesummary task and this task keeps
> iterating all elements from directoryTable without considering the fact
> loading all elements in memory and if elements are more in number, this may
> cause OOM... After I checked the OM rocks DB of cluster, I can see millions
> of directories and they all will be loaded in memory by NameSpaceSummary task
> for FSO buckets to store and flush the data in NameSpaceSummaryTable of recon
> sql DB. This needs fix.
