Hi all!
Suddenly U8 (from Visual Studio) randomly (?) crashes ... without clear reason. Most recently when simply returning to the previous page in browser. On Lucene ... No idea what to do. Could it be a damaged configuration? Or how to reset. It is terribly delaying. No problem on production site. Thanks in advance.

The error reported
Lucene.Net.Index.MergePolicy.MergeException HResult=0x80131501 Message=Exception of type 'Lucene.Net.Index.MergePolicy+MergeException' was thrown.
