Have you tried letting Solr use its default garbage collection settings
instead of G1? Have you tried Java 11? Java 9 is one of the releases
without long term support, so as Erick says, it is not recommended.

Our current setup is as follows:

I would try JDK11 - it works much better than JDK9 in general.
I don‘t think JDK13 with ZGC will bring you better results. There seems to be
sth strange with the JDk version or Solr version and

Solr 7.x has been tested with Java 9 and should work with no problems.

Shawn,
There won't be a Java 10, we'll get Java 18.3 instead. After 9 it is a guess
when CMS and friends are gone.
