Hi Yonik,
I've been attempting to fix the SUBREADER insanity in our custom
component, and have made perhaps some progress (or is this worse?) -
I've gone from SUBREADER to VALUEMISMATCH insanity:
---snip---
entries_count : 12
entry#0 :
Yonik, et al.
I believe I found the section of code pushing me into 'insanity' status:
---snip---
int[] collapseIDs = null;
float[] hotnessValues = null;
String[] artistIDs = null;
try {
collapseIDs =
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---

Hi Aaron, here there is some information about the insanity count:
http://wiki.apache.org/solr/SolrCaching#The_Lucene_FieldCache
As for the SUBREADER type, the javadocs say:
Indicates an overlap in cache usage on a given field in sub/super readers.
This probably means that you are using the same
Hi Tomás,
This probably means that you are using the same field for faceting and for
sorting (tf_normalizedTotalHotttnesss), sorting uses the segment level
cache and faceting uses by default the global field cache. This can be a
problem because the field is duplicated in cache, and then it
The other thing to realize is that it's only insanity if it's
unexpected or not-by-design (so the term is rather mis-named).
It's more for core developers - if you are just using Solr without
custom plugins, don't worry about it.

Some function queries also use the field cache. I *think* those usually use
the segment level cache, but I'm not sure.

That part is interesting... if true, then the type of insanity you
saw should be impossible, and either the insanity detection or
something else is broken.
