>>  if (System.DateTime.Now.Hour == 21)

Are you sure that your code does not call optimize (for ex, at 21:00:01 ,  21:00:02 etc,) while another optimization is in progress?

> We are using the Lucene search engine a couple of months, on the first approach seems a very good and high-performance engine.
> We are using the your "Lucene.net.dll"API version 2.0.0.4. 
> We have an index with 20GB approximately, all hours are added news docs to index and a time per day the optimization is done at 9 pm.
> During a couple of days everything ran fine even a day that optimization process "writer.Optimize();" return the following exception:
> "Source array was not long enough. Check srcIndex and length, and the array´s lower bounds."
> Here you can find some parts of my code:
> Document doc; doc = null;
> IndexWriter writer; writer = null;
> writer = new IndexWriter(strArticleIndexFolder, new StandardAnalyzer(), isNew);
> writer.SetMergeFactor(1000);
> writer.SetMaxMergeDocs(10000);
> foreach (ArticleIndexFull objArticleIndex in lstArticleIndexFull)
> {
> doc = new Document();
> doc.Add(newField(O4kFreeSearchTag.ArticleLuceneId,objArticleIndex.ArticleIndexFullId.ToString(), Field.Store.YES, Field.Index.TOKENIZED, Field.TermVector.YES));
> doc.Add(newField(O4kFreeSearchTag.ArticleId,objArticleIndex.ArticleId.ToString(),Field.Store.YES, Field.Index.TOKENIZED, Field.TermVector.YES));
> doc.Add(newField(O4kFreeSearchTag.ProductionDate,FactoryBLL.ArticleIndex.ClearCharStream(AlphaNumeric.ConvertToString(objArticleIndex.ProductionDate.ToString("yyyyMMdd",System.Globalization.CultureInfo.GetCultureInfo("en-US")),String.Empty)),Field.Store.NO, Field.Index.TOKENIZED, Field.TermVector.YES));
> ....
> writer.AddDocument(doc);
> }
> if (System.DateTime.Now.Hour == 21)
> {
> writer.Optimize();
> }
> writer.Close();
> If we migrate to last version available in this case the 2.4.3 my problem will be fixed?
> Has my code any kind of problem?
> We will appreciate your help.
