Something appears to be wrong with your _X.tii file (inside the
compound file).
Can you post the code that recreates this broken index?
Since it appears to be repeatable, could you regenerate your index
with compound file off, confirm the problem still happens, and then
post the _X.tii file? I can try to look at it.

Hello,
I'm using Lucene 2.3.2 and had no problems untill now.
But now I got an corrupt index. When searching, a
java.lang.OutOfMemoryError is thrown. I've wrote the following test
program:
private static void search(String index, String query) throws
CorruptIndexException, IOException, ParseException
{
IndexReader reader = IndexReader.open(index);
//reader.setTermInfosIndexDivisor(10);
Collection col =
Reader.getFieldNames(IndexReader.FieldOption.INDEXED);
Iterator it = col.iterator();
String[] fields = new String[col.size()];
int i = 0;
while(it.hasNext())
{
fields[i] = (String)it.next();
System.out.println("field["+i+"]: "+fields[i]);
i++;
}
Analyzer analyzer = new StandardAnalyzer();
MultiFieldQueryParser parser = new MultiFieldQueryParser(fields,
analyzer);
parser.setAllowLeadingWildcard(true);
Query quer = parser.parse(query);
System.out.println("Query: "+quer.toString());
quer = quer.rewrite(reader);
System.out.println("rewritten Query: "+quer.toString());
reader.close();
}
If reader.setTermInfosIndexDivisor() is commented out, the
stacktrace looks like this:
Exception in thread "main" java.lang.OutOfMemoryError: Java heap space

The index has a size of 59 MB, so it is weird to get an
OutOfMemoryException. So with reader.setTermInfosIndexDivisor() set
to 10, the stacktrace looks like:
java.lang.IndexOutOfBoundsException: Index: 103, Size: 54

Recreating the index didn't solve the problem. And I have no idea
for solving it, so every help is greatly appreciated.
Thanks in advance.
