Hoan Tran Van updated SOLR-13814:
---------------------------------
Description:
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 node use DIH for importing from
Oracle. I compare some metrics but there are not much different (except server
1 have less core than others)
