[jira] Created: (LUCENENET-191) Memory Leak Lucene.Net-2.3.2.1
Memory Leak Lucene.Net-2.3.2.1
------------------------------
Key: LUCENENET-191
URL: https://issues.apache.org/jira/browse/LUCENENET-191
Project: Lucene.Net
Issue Type: Bug
Environment: Operating System: Microsoft Windows XP Professional version 2002, Service Pack 2
Software platform: Visual studio .Net 2008, Framework-3.5
Reporter: Ashish Kr Dey
I am using Lucene.Net-2.3.2.1 in my project. My project also supporting multithreading environment. Lucene Indexing service is working as Windows Service. Problem is when the service is running, it's memory blockage is gradually increasing. So after some hours, it shows a memory of 150 mb in Task Manager where as it start with 13 mb.so it has a memory increasing behavior. I identified by dotTrace Profiler that in Lucene.Net there are some methods and objects that increased the memory. From Call Tree one of my dotTrace out put identify that Index(), Segment() related functions hold's memory increased as long as the service perform. So it at a time, it will crash the system.
Please help me how i can recover my application from this memory leakage.

--------------------------------
I tried (Lucene.Net-2.3.2.1) with 10M documents and didn't see any memory leakage.

--------------------------------
Memory usage difference between the start and end of a program does not say much. You should observe the memory while documents are indexed. (like printing some mem-infos with every 1000 docs indexed)
