Lucene.NET (Revision: 603121) is leaking memory
-----------------------------------------------
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.
