    This indexReader is Closed: Lucene AlreadyClosedException

    We have an Umbraco 7.9 site on Windows Server 2008 R2.

    We upgraded it from 7.5.8 two months ago. Now, on server reboot or occasionally on regularly scheduled app pool recycles, the Examine index doesn't return search results (on about 50% of the searches). This happens almost every week, during one of the IIS app pool recycles.

    ERROR Umbraco.Web.PublishedCache.XmlPublishedCache.PublishedMediaCache - Could not load data from Examine index for media, the app domain is most likely in a shutdown state Lucene.Net.Store.AlreadyClosedException: this IndexReader is closed at Lucene.Net.Index.IndexReader.EnsureOpen() at Lucene.Net.Index.DirectoryReader.GetFieldNames(FieldOption fieldNames) at Examine.LuceneEngine.Providers.LuceneSearcher.GetSearchFields() in C:\projects\examine-qvx04\src\Examine\LuceneEngine\Providers\LuceneSearcher.cs:line 248 at UmbracoExamine.UmbracoExamineSearcher.GetSearchFields() at Examine.LuceneEngine.Providers.BaseLuceneSearcher.CreateSearchCriteria(String type, BooleanOperation defaultOperation) in C:\projects\examine-qvx04\src\Examine\LuceneEngine\Providers\BaseLuceneSearcher.cs:line 117 at UmbracoExamine.UmbracoExamineSearcher.CreateSearchCriteria(String type, BooleanOperation defaultOperation) at Umbraco.Web.PublishedCache.XmlPublishedCache.PublishedMediaCache.GetUmbracoMediaCacheValues(Int32 id)

    Hi Alex, If you go to Developer > XML Data Integrity Report, are all of your XML Cache data OK? John

    We had to fix the XML Cache to get the indexes to stop locking up. Not sure if you are experiencing the same issue.
