Shai Erera commented on SOLR-9290: ---------------------------------- bq. I thought that hypothesis holds only after SOLR-8533. Are you saying you also saw it on 5.3.2? If so, what are the values that are set for these properties there? We definitely do not see the problem with 5.4.1, but we didn't test prior versions. We posted at the same time, I read your answer above. I wonder why we don't see the problem with 5.4.1. I mean, we do see CLOSE_WAITs piling, but stop at ~100 (200 for the leader). > TCP-connections in CLOSE_WAIT spikes during heavy indexing when SSL is enabled > ------------------------------------------------------------------------------ > > Key: SOLR-9290 > URL: https://issues.apache.org/jira/browse/SOLR-9290 > Project: Solr > Issue Type: Bug > Security Level: Public(Default Security Level.
