Why does Lucene cause OOM when indexing large files?

Question

I’m working with Lucene 2.4.0 and the JVM (JDK 1.6.0_07). I’m consistently receiving OutOfMemoryError: Java heap space, when trying to index large text files.<

Answer 1

Profiling is the only way to determine, such large memory consumption.

Also, in your code,you are not closing the Filehandlers,Indexreaders,Inderwriters, perhaps the culprit for OOM,
