Hi all,

There was an issue posted on the old forum about the back-end Lucene index getting massive in filesize:

http://forum.umbraco.org/yaf_postst9142_datasystemUmbracoIndexDontDelete-folder-1000-MB.aspx

I'm experiencing this on one of my Umbraco (v4) installs ... but the index has got up to 6Gb!!!

The umbracoLog table it littered with Lucene errors ... but they don't make much sense to me.

Examples of error:

Error indexing node: System.IO.IOException: read past EOF     at Lucene.Net.Store.BufferedIndexInput.Refill()     at Lucene.Net.Store.BufferedIndexInput.ReadByte()     at Lucene.Net.Store.IndexInput.ReadInt()     at Lucene.Net.Index.SegmentTermEnum..ctor(IndexInput i, FieldInfos fis, Boolean isi)     at Lucene.Net.Index.TermInfosReader..ctor(Directory dir, String seg, FieldInfos fis)     at Lucene.Net.Index.SegmentReader.Initialize(SegmentInfo si)     at Lucene.Net.Index.SegmentReader.Get(Directory dir, SegmentInfo si, SegmentInfos sis, Boolean closeDir, Boolean ownDir)     at Lucene.Net.Index.IndexWriter.MergeSegments(Int32 minSegment, Int32 end)     at Lucene.Net.Index.IndexWriter.MergeSegments(Int32 minSegment)     at Lucene.Net.Index.IndexWriter.FlushRamSegments()     at Lucene.Net.Index.IndexWriter.Close()     at umbraco.cms.businesslogic.index.Indexer.IndexNode(Guid ObjectType, Int32 Id, String Text, String UserName, DateTime CreateDate, Hashtable Fields, Boolean Optimize)     at umbraco.cms.businesslogic.web.Document.Index(Boolean Optimze)

and

Error indexing node: (System.NullReferenceException: Object reference not set to an instance of an object. at Lucene.Net.Index.TermVectorsWriter.AddAllDocVectors(TermFreqVector[] vectors) at Lucene.Net.Index.SegmentMerger.MergeVectors() at Lucene.Net.Index.SegmentMerger.Merge() at Lucene.Net.Index.IndexWriter.MergeSegments(Int32 minSegment, Int32 end) at Lucene.Net.Index.IndexWriter.Optimize() at umbraco.cms.businesslogic.index.Indexer.IndexNode(Guid ObjectType, Int32 Id, String Text, String UserName, DateTime CreateDate, Hashtable Fields, Boolean Optimize))

Any ideas?

Thanks in advance, Lee.
