Memory line in status output

2020-10-12 Thread Ryan W
Hi all, What is the meaning of the "memory" line in the output when I run the solr status command? What controls whether that memory gets exhausted? At times if I run "solr status" over and over, that memory number creeps up and up and up. Presumably it is not a good thing if it moves all the

Solr doesn’t manage this at all, it’s the JVM’s garbage collection that occasionally kicks in. In general, memory creeps up until the GC threshold is set (which there are about a zillion parameters that you can set) and then GC kicks in. Generally, the recommendation is to use the G1GC collector

Thanks. How do I activate the G1GC collector? Do I do this by editing a config file, or by adding a parameter when I start solr? Oracle's docs are pointing me to a file that supposedly is at instance-dir/OUD/config/java.properties, but I don't have that path. I am not sure what is meant by
