-----------------------------------
Resolution: Information Provided
The JIRA issue tracker is not a support portal. Please raise this question on
the user's list at solr-u...@lucene.apache.org, see:
(http://lucene.apache.org/solr/community.html#mailing-lists-irc) there are a
_lot_ more people watching that list who may be able to help and you'll
probably get responses much more quickly.
If it's determined that this really is a code issue or enhancement to Solr and
not a configuration/usage problem, we can raise a new JIRA or reopen this one.

> Key: SOLR-13814
> URL: https://issues.apache.org/jira/browse/SOLR-13814
> Project: Solr
> Issue Type: Improvement
> Security Level: Public(Default Security Level. Issues are Public)
> Components: SolrCloud
> Affects Versions: 6.6
> Reporter: Hoan Tran Van
> Priority: Minor
>
> I have a SolrCloud with 9 nodes on 9 physical servers. the server 2, 4, 5
> usually have high RAM usage > 92%. I restart but they will increase after 1-3
> days, others servers never reach 90% RAM. 9 severs are similar. 9 solr nodes
> have same solr.in.sh configuration. 9 solr nodes use DIH for importing from
> Oracle. I compare some metrics but there are not much different (except
> server 1,7 have less core than others). How to rebalance ram usage for 9
> servers?
