Subject Understanding fieldCache SUBREADER "insanity"
Date Wed, 19 Sep 2012 18:16:31 GMT
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:

insanity_count : 1
insanity#0 : SUBREADER: Found caches for descendants of

How can I decipher what this means and what, if anything, I should do
to fix/improve the "insanity"?
