>                 Key: LUCENENET-106
>                 URL: https://issues.apache.org/jira/browse/LUCENENET-106
>             Project: Lucene.Net
>          Issue Type: Bug
>         Environment: .NET 2.0
>            Reporter: Anton K.
>            Priority: Critical
>
> readerCache Hashtable field (see FieldCacheImpl.cs) never releases some hash items that have closed IndexReader object as a key. So a lot of Term instances are never released.
> Java version of Lucene uses WeakHashMap and therefore doesn't have this problem.
> This bug can be reproduced only when Sort functionality used during search. 
> See following link for additional information.
> http://www.gossamer-threads.com/lists/lucene/java-user/55681
> Steps to reproduce:
> 1)Create index
> 2) Modify index by IndexWiter; Close IndexWriter
> 3) Use IndexSearcher for searching with Sort; Close InexSearcher
> 4) Go to step 2
> You'll get OutOfMemoryException after some time of running this algorithm.
