I think this is the same bug as in http://issues.apache.org/jira/browse/LUCENENET-117 .
Can you try the patch?

Lucene 2.3.1(a?) - Unhandled System.NullReferenceException  In Lucene.Net.Index.DocumentsWriter.CompareText
-----------------------------------------------------------------------------------------------------------

                 Key: LUCENENET-125
                 URL: https://issues.apache.org/jira/browse/LUCENENET-125
             Project: Lucene.Net
          Issue Type: Bug
         Environment: Microsoft Visual Studio 2005, XP Pro
            Reporter: Ken Katzgrau


When creating a test index of a 1,000,000 documents, I encountered a null reference exception
originating from the document writer approximately every 80,000 documents. The code producing
this error is:

    class Program
    {
        static void Main(string[] args)
        {
            IndexWriter iw = new IndexWriter(@"C:\TestIndex", new WhitespaceAnalyzer(), true);
            Document d;
            Field f;

            for (int i = 0; i < 100000; i++)
            {
                if (i % 10000 == 0) Console.WriteLine("Doc: " + i);

                d = new Document();

                f = new Field("Field1", "Content " + i, Field.Store.YES, Field.Index.UN_TOKENIZED);
                d.Add(f);

                f = new Field("Field2", "Content " + i, Field.Store.YES, Field.Index.UN_TOKENIZED);
                d.Add(f);

                iw.AddDocument(d); *Exception occurs here
            }

            Console.WriteLine(iw.DocCount());
            Console.ReadKey();
            iw.Close(); *If the exception is caught, the IndexWriter iw becomes null
        }
    }

The exception is:

System.NullReferenceException was unhandled
  Message="Object reference not set to an instance of an object."
