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
