[jira] [Commented] (SOLR-14201) some SolrCore are not released after being removed

    [ https://issues.apache.org/jira/browse/SOLR-14201?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17545823#comment-17545823 ]

Hello [~gbierner]!
{quote}I am seeing the same issue in solr 8.8. References to SolrCore stay in memory even after the core is removed.

Thanks for sharing that the issue also happens in the 8.8 version.

Thinking aloud re: possible next steps here:
 * Is the issue also still happening in the 9.0 version or on the latest {{main}} development branch?

 * Is the Solr running in cloud-mode or standalone?

 * The reproducting steps above reference a custom config {{collection.configName=seafas}} and include adding of documents. Is the issue happening if no documents are added and when using one of the out-of-the-box configsets?

{code:java}
./gradlew dev

./solr/packaging/build/solr-10.0.0-SNAPSHOT/bin/solr start -e cloud -noprompt
       
# ...

./solr/packaging/build/solr-10.0.0-SNAPSHOT/bin/solr stop -all
{code}
or
{code:java}
./gradlew dev

 ./solr/packaging/build/solr-10.0.0-SNAPSHOT/bin/solr start -e techproducts
       
# ...

./solr/packaging/build/solr-10.0.0-SNAPSHOT/bin/solr stop -all
{code}

Hope that helps.
