Hi, I'm in a bit of a crisis here. Trying to deploy a new search on an ecommerce website which has been tested (but not stress tested). The core has been running for years without any performance problems but we have now changed two things:
1) started using group.facet=true in a rather complicated query - see below 2) added a new core with suggester component Solr version was 5.2, upgraded to 5.5.4 to try, no improvement. What happens under real load is the query response times start getting higher > 10000 and most requests end up like this: org.apache.solr.servlet.HttpSolrCall; Unable to write response, client closed connection or we are shutting down Could it be this issue https://issues.apache.org/jira/browse/SOLR-4763 ? And if so, would upgrading to 6.4 help or changing the app to start using JSON.facet ? Any help would be greatly appreciated.
