> 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."
