Subject [jira] Created: (LUCENE-552) NPE during mergeSegments
Date Fri, 21 Apr 2006 14:10:05 GMT
NPE during mergeSegments
------------------------

         Key: LUCENE-552
         URL: http://issues.apache.org/jira/browse/LUCENE-552
     Project: Lucene - Java
        Type: Bug

  Components: Index  
    Versions: 2.0    
 Environment: 2.0-rc1-dev

    Reporter: Ole Kværnø


The JVM stops with a NPE after running for about 6-8 hours, indexing about 500.000 articles.
After a restart of the JVM, the problematic merge seems to complete OK.

Exception in thread "Thread-4" java.lang.NullPointerException
