Mirza Hadzic commented on LUCENE-1091:
--------------------------------------
I am inclined to think this is JVM 6 issue. When running TestOOM with JVM
parameters -Xms200m -Xmx200m , it easily increases virtual memory usage past
500MB ! Obviously, JVM have no idea how much memory it actually uses, and log
from TestOOM suggest this is the case. Running System.gc() every 100 added
documents changes nothing, just like I expected.
Attached is screenshot of my task list on XP sorted by VM usage when running
TestOOM. Second java.exe is Netbeans (CPU: 0%), ignore that. TestOOM is
java.exe using 48-50% all the time (I have dual-core, so it uses one full CPU,
which is true/OK).

> This little program eats incrementally 2MB of virtual RAM per each 1000
> documents indexed, only when Field.Index.TOKENIZED used :
> public Document getDoc() {
> Document document = new Document();
> document.add(new Field("foo", "foo bar", Field.Store.NO,
> Field.Index.TOKENIZED));
> return document;
> }
> public Document run() {
> IndexWriter writer = new IndexWriter(new File(jIndexFileName), new
> StandardAnalyzer(), true);
> for (int i = 0; i < 1000000; i++) {
> writer.addDocument(getDoc());
> }
> }
