> Reporter: Dirk Högemann
> Priority: Minor

> Our production Solr-Slaves-Cores (we have about 40 Cores (each has a moderate size about 10K documents to 90K documents)) produce many exceptions of type:
> 014-11-05 15:06:06.247 [searcherExecutor-158-thread-1] ERROR org.apache.solr.search.SolrCache: Error during auto-warming of key:org.apache.solr.search.QueryResultKey@62340b01:org.apache.solr.search.EarlyTerminatingCollectorException

> at least this ERRORs broke nothing see
> https://github.com/apache/lucene-solr/blob/20f9303f5e2378e2238a5381291414881ddb8172/solr/core/src/java/org/apache/solr/search/FastLRUCache.java#L165
> anyway, here are two usability issues:
> - of key:org.apache.solr.search.QueryResultKey@62340b01 lack of readable
> toString()
> - I don't think regeneration exceptions are ERRORs, they seem WARNs for me
> or even lower. also for courtesy, particularly
> EarlyTerminatingCollectorExcepions can be recognized, and even ignored,
> providing SolrIndexSearcher.java#L522
> -> Maybe the log-level could be set to info/warn, if there are no implications on the functionality?
