Different garbage collector configuration? It does not mean that Solr uses more
memory if it is occupied - it could also mean that the JVM just kept it
reserved for future memory needs.

Comparing memory consumption (real, not virtual) of quiesent Solr v8.0 and
prior with Solr v8.1.0 reveals the older versions use about 1.6GB on my systems
but v8.1.0 uses 4.5 to 5+GB. Systems used are SUSE Linux, with Oracle JDK v1.8
and openjdk v10. This is a major memory consumption issue. I have seen no
mention of it in the docs nor forums.

The garbage collector was on my mind as well (in a msg sent just
before yours). These numbers are easy to verify, just by using "top".
They say allocated, meaning Java owns it, no matter what Java does with
it. Java does not own the machine; there are other useful activities to
tend as well.
Let's find the problem and cure it.
Thanks,
