Simon Svensson commented on LUCENENET-482: ------------------------------------------ The 2.3.2-release is about three years old (based on history.txt). Are you able to try a later version, preferably the latest 2.9.4 release? The source for BufferedIndexInput.cs (line 176) allocates a byte array, with the default size of 1 KiB. This is unlikely to fail (unless you're running with severe memory restraints). Can you provide us with a larger stack trace so we can track down the allocation path, and find if the created BufferedIndexInput uses a bigger buffer size than the default 1 KiB. Older releases are tagged and available at https://svn.apache.org/repos/asf/incubator/lucene.net/tags/. There are, however, distributed as source code and are not available as precompiled assemblies. > Lucene out of Memory issue > -------------------------- > > Key: LUCENENET-482 > URL: https://issues.apache.org/jira/browse/LUCENENET-482 > Project: Lucene.Net > Issue Type: Bug > Environment: Windows server 2003 and lucene .Net ver 2.3.2 > Reporter: Suraj Pant > > Hi We have recently tried to upgraded to lucene ver 2.3.2, at current we are > using ver 1.9.1.
