Thanks [~cpoerschke]
To reproduce this issue, just keep creating new collections
{code:java}
while true; do ./import.sh; sleep 10; done
#import.sh
#!/bin/bash -e
HOST=http://localhost:8983/solr
PREV_COLLECTION=$(http "$HOST/admin/collections?action=LISTALIASES" | jq -r ".aliases.SGFAS")
COLLECTION="next_$(gdate +%H%M%S)"
# COLLECTION="next_1029"
echo "Create new collection = $COLLECTION"
http POST "$HOST/admin/collections?action=CREATE&name=$COLLECTION&collection.configName=seafas&numShards=1"
echo "Push data to new collection"
cat docs.xml | http POST "$HOST/$COLLECTION/update?commitWithin=1000&overwrite=true&wt=json" "Content-Type: text/xml"
echo "Optimize"
http "$HOST/$COLLECTION/update?optimize=true&maxSegments=1&waitSearcher=false"
echo "Update alias"
http "$HOST/admin/collections?action=CREATEALIAS&collections=$COLLECTION&name=SGFAS"
echo "Delete previous collection = $PREV_COLLECTION"
http "$HOST/admin/collections?action=DELETE&name=$PREV_COLLECTION"
{code}
I also tried to remove all plugins, but the issue still persists.
Classes.loaded keeps increasing.
{code:java}
❯ http "http://localhost:8983/solr/admin/metrics" | jq '.metrics."solr.jvm"."classes.loaded"'
8428
❯ http "http://localhost:8983/solr/admin/metrics" | jq '.metrics."solr.jvm"."classes.loaded"'
9323
{code}
