Hi all, In reviewing a solr instance with somewhat variable performance, I noticed that its fieldCache stats show an insanity_count of 1 with the insanity type SUBREADER:
---snip--- insanity_count : 1 insanity#0 : SUBREADER: Found caches for descendants of ReadOnlyDirectoryReader(segments_k _6h9(3.3):C17198463)+tf_normalizedTotalHotttnesss 'ReadOnlyDirectoryReader(segments_k _6h9(3.3):C17198463)'=>'tf_normalizedTotalHotttnesss',float,org.apache.lucene.search.FieldCache.NUMERIC_UTILS_FLOAT_PARSER=>[F#1965982057 'ReadOnlyDirectoryReader(segments_k _6h9(3.3):C17198463)'=>'tf_normalizedTotalHotttnesss',float,null=>[F#1965982057 'MMapIndexInput(path="/io01/p/solr/playlist/a/playlist/index/_6h9.frq")'=>'tf_normalizedTotalHotttnesss',float,org.apache.lucene.search.FieldCache.NUMERIC_UTILS_FLOAT_PARSER=>[F#1308116426 ---snip--- How can I decipher what this means and what, if anything, I should do to fix/improve the "insanity"? Thanks, Aaron
