    Getting System.IO error from Lucene Index

    Hey I am hosting an Umbraco instance on a shared hosting server and periodically with seemingly no rhyme or reason I get the following exception and stack trace. The site remains in this state until I manually go and reset the apppool after which everything works fine again. I am at a lost and any feedback would be very much appreciated.

    2015-08-04 00:41:53,782 [7] ERROR Umbraco.Core.UmbracoApplicationBase - [Thread 148] An unhandled exception occurred System.IO.IOException: The device is not ready.

    Depending on your hosting provider and how they store files on the file system, you might be able to fix this. See my response here: https://our.umbraco.org/forum/getting-started/installing-umbraco/20999-Disable-Lucene-Examine#228320

    We are seeing this error on the Azure appp serivce :

    An unhandled exception occurred and the process was terminated

    at Lucene.Net.Store.SimpleFSDirectory.CreateOutput at Lucene.Net.Index.CompoundFileWriter.Close at Lucene.Net.Index.DocumentsWriter.CreateCompoundFile at Lucene.Net.Index.IndexWriter.DoFlushInternal at Lucene.Net.Index.IndexWriter.DoFlush at Lucene.Net.Index.IndexWriter.PrepareCommit at Lucene.Net.Index.IndexWriter.Commit at Examine.LuceneEngine.Providers.LuceneIndexer.IndexCommiter.TimerRelease at System.Threading.ExecutionContext.RunInternal at System.Threading.ExecutionContext.Run at System.Threading.TimerQueueTimer.CallCallback at System.Threading.TimerQueueTimer.Fire at System.Threading.TimerQueue.FireNextTimers

    and sometimes this :
