Hi, Adding more details to my previous email. We are using Solr 8.4 . In our solr config we have autoCommit as hardcommit with opensearcher =false.and we do NOT have autosoftCommit Or explicit soft commit. Hence I presume that new searched won't be opened to invalidate the field cache.
But it looks that field cache is getting cleared sometimes. Please let me know if there is any other possibility here that could have cleared the field cache. Our jvm heap size is 24Gb. Thanks, Poorna
