--------------------------------
Summary: Can't open IndexReader, get OutOFMemory Exception
Key: LUCENENET-488
URL: https://issues.apache.org/jira/browse/LUCENENET-488
Project: Lucene.Net
Issue Type: Bug
Components: Lucene.Net Core
Affects Versions: Lucene.Net 2.9.4g
Environment: Windows server 2008R2
Reporter: Steven
Have build a large database with ~1Bn records (2 items per document) it has
size 200GB on disk. I managed to write the indexe by chunking into 100,000
blocks as I ended up with some threading issues (another bug submission).
Anyway the index is built but I can't open it and get a memory exception
(process explorer gets to 1.5GB allocated before it dies but not sure how
reliable that is, but do know there is plenty more RAM left on the box).
Stack trace below:
System.OutOfMemoryException: Exception of type 'System.OutOfMemoryException' was
thrown.
