Hello, We are running our solr 6.4.2 instance on a single node without zookeeper. So, we are not using solr cloud. We have been ingesting about 50k messages per second into this instance spread over 4 cores.
When we looked at the heapdump we see that it has there are around 385 million instances of VersionBucket objects taking about 8gb memory. This number seems to grow based on the number of cores into which we are ingesting data into.PFA a screen cap of heap recording. Browsing through the jira list we saw a similar issue - https://issues.apache.org/jira/browse/SOLR-9803 This issue is recently resolved by Erick. But this issue seems be specifically tied to SolrCloud mode and Zookeeper. We are not using any of these. So, we are thinking this could be another issue. Any one has ideas on what this could be and if there is a fix for it? Thanks Sundeep
