Memory leak on Lucene.net 2.3.2

[C# Programming]

Dear friends

I am using lucene.net 2.3.2 for indexing, but I am facing memory leakage problem in many methods(GetPosting(Posting []), AddPosition(Token), ProcessDocument(Analyzer) etc) using dotTrace profiler. How do I solve this problem? Can anybody say in which version of lucene.net, no memory leakage problem occurs?

Thanks in advance Susanta
