Solr Support Diagnostic: Common Issues & Fixes

Issue: Solr OOM / OutOfMemoryError

Root cause: JVM heap too small, cache misconfiguration, or unbounded facet queries. Our engineers analyze heap dumps and tune GC settings to eliminate OOM errors.

Issue: Slow Search Queries (>500ms)

Root cause: Missing cache warming, poor query structure, large result sets, or unoptimized faceting. We profile queries with Solr’s request handler stats and apply targeted fixes.

Issue: SolrCloud Split-Brain

Root cause: Network partition causing replicas to elect conflicting leaders. We perform controlled shard recovery, resync replicas, and implement network topology fixes.

Issue: Relevancy Degradation

Root cause: Schema changes affecting IDF scoring, boost factor drift, or field weight misalignment. We run A/B testing with Solr’s LTR plugin and restore expected ranking.

Issue: High CPU on Solr Nodes

Root cause: Unthrottled indexing, expensive facets, missing filter caching, or segment merge storms. We tune merge policies, apply filter caching, and reduce per-query CPU cost.
