Ok Erick,
Thanks for your quick answer.
FSDirectory will, indeed, store the index on disk. However,
when *using* that index, lots of stuff happens. Specifically:
When indexing, there is a buffer that accumulates documents
until it's flushed to disk. Are you indexing?
When searching (and this is the more important part), various
caches are used to speed up searches. A substantial part of
your index may be held in memory at various points.
70M just isn't very much memory, I think you'll have to get
more if at all possible.
Best
Erick

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?
Is it correct? I'm using FSDirectory because I haven´t a big amount of RAM
memory.
Thanks.
