Hi, I am using Lucene 2.9.4 with FSDirectory. My index has 80 thousand documents (each document has 12 fields). My jvm has 70Mb of RAM memory (limited by my hosting). I am getting various OutOfMemoryError. I ran jmap and I got:
num #instances #bytes Class description -------------------------------------------------------------------------- 1: 275926 32074080 char[] 2: 657724 31570752 org.apache.lucene.index.FreqProxTermsWriter$PostingList 3: 200 16094896 org.apache.lucene.index.RawPostingList[] The Lucene is consuming 47Mb of RAM memory. Why there is this excessive memory consumption in FSDirectory? Thanks.
