spellcheck causing Core Reload to hang

[Raheel Hasan]

Hi,

after a lot of investigation today, I found that its the spellcheck
component which is causing the issue. If its turned off, all will run well
and core can easily reload. However, when the spellcheck is on, the core
wont reload instead hang forever.

Then the only way to get the project back alive is to stop solr, and delete
the data folder then start solr again.

Here are the solr config settings for spell check:

<requestHandler name="/select" class="solr.SearchHandler">
<lst name="defaults">
       <!-- Spell checking defaults -->
       <str name="spellcheck.dictionary">default</str>
       <str name="spellcheck">on</str>
       <str name="spellcheck.count">5</str>
       <str name="spellcheck.onlyMorePopular">false</str>
       <str name="spellcheck.maxResultsForSuggest">5</str>
       <str name="spellcheck.alternativeTermCount">2</str>
       <str name="spellcheck.extendedResults">false</str>

       <str name="spellcheck.collate">true</str>
       <str name="spellcheck.maxCollations">3</str>
       <str name="spellcheck.maxCollationTries">3</str>
       <str name="spellcheck.collateExtendedResults">true</str>
</lst>

     <arr name="last-components">
       <str>spellcheck</str>
     </arr>
</requestHandler>


<searchComponent name="spellcheck" class="solr.SpellCheckComponent">

    <str name="queryAnalyzerFieldType">text_en_splitting</str>

    <lst name="spellchecker">
      <str name="name">default</str>
      <str name="field">location_details</str>
      <str name="classname">solr.DirectSolrSpellChecker</str>
      <str name="buildOnCommit">true</str>
      <float name="accuracy">0.5</float>
      <float name="thresholdTokenFrequency">.01</float>
      <int name="maxEdits">1</int>
      <int name="minPrefix">3</int>
      <int name="maxInspections">3</int>
      <int name="minQueryLength">4</int>
      <float name="maxQueryFrequency">0.001</float>
    </lst>

  </searchComponent>


Here is the field from schema:
<field name="location_details" type="text_en_splitting" indexed="true"
stored="false" required="false" />
