We are running a DW 9.4.9 with Rapido 2.0 and have many problems with the index.
All the time we get this message:
Lock obtained at Lucene.Net.Store.Lock.Obtain(Int64 lockWaitTimeout) at Lucene.Net.Index.IndexWriter.Init(Directory d, Analyzer a, Boolean create, IndexDeletionPolicy deletionPolicy, Int32 maxFieldLength, IndexingChain indexingChain, IndexCommit commit) at Lucene.Net.Index.IndexWriter..ctor(Directory d, Analyzer a, Boolean create, MaxFieldLength mfl) at Dynamicweb.Indexing.Lucene.LuceneIndexWriter.Open(Boolean openForAppend) at Dynamicweb.Ecommerce.Indexing.ProductIndexBuilder.Build(IIndexWriter writer, Tracker tracker)
Its not possible to run the index at the moment, and the only fix we had luck with so far is to create a new instance, but getting tired of doing that...
