Question for System.AccessViolationException in Lucene.NET 

Dear All,

 

I have been using Lucene.NET v2.9.2 in prod for a couple of years without
any issue but recently it began to throw the AccessViolationException error
once in a few weeks. Does anyone know what would cause it? 

 

Here is the stacktrace:

 

Description: The process was terminated due to an unhandled exception.

Exception Info: System.AccessViolationException

Stack:

   at Lucene.Net.Util.ScorerDocQueue.TopNextAndAdjustElsePop()

   at Lucene.Net.Search.DisjunctionSumScorer.AdvanceAfterCurrent()

   at Lucene.Net.Search.DisjunctionSumScorer.Advance(Int32)

   at Lucene.Net.Search.BooleanScorer2.Advance(Int32)

   at Lucene.Net.Search.ConjunctionScorer.Advance(Int32)

   at Lucene.Net.Search.BooleanScorer2.Advance(Int32)

   at Lucene.Net.Search.ConjunctionScorer.DoNext()

   at Lucene.Net.Search.ConjunctionScorer.NextDoc()

   at Lucene.Net.Search.BooleanScorer2.Score(Lucene.Net.Search.Collector)

   at Lucene.Net.Search.IndexSearcher.Search(Lucene.Net.Search.Weight,
Lucene.Net.Search.Filter, Lucene.Net.Search.Collector)

   at Lucene.Net.Search.Searcher.Search(Lucene.Net.Search.Query,
Lucene.Net.Search.Collector)

 

Best Regards,

 

Frank Yu

Itamar,

Thanks for your reply. I will run the CheckIndex. Also search was working
fine after the application got restarted. I am suspecting that it shall stop
working if the Lucene index got corrupted. 

Thanks,

Frank Yu

Corrupted index perhaps? can you run CheckIndex from the 2.9 version (
https://github.com/apache/lucene.net/blob/Lucene.Net_2_9_4g/src/core/Index/C
heckIndex.cs
 )?
