Hi. We're running Solr 6.6.1 (SolrCloud, 3 nodes). Recently I noticed
it became significantly slower to respond and did some basic checks on
servers. There is little IO, a bit of CPU usage (110% user, 3090%
idle),
but one thing is very strange - the resident memory usage of the Solr.
Despite the -Xms=8G and -Xmx=8G and despite that Solr UI shows only
4Gb heap used, the top and atop shows RSIZE=100Gb+ used by Solr.
Can you share the "top" screen so we can see specifically how it looks?
Run top, press shift-M to sort by memory usage, then grab a screenshot.
Solr is usually one of the big memory consumers, so it should be at or
near the top of the list. Use a file sharing website to share the
screenshot.
