FileNotFoundException: a typical stack trace

[petite_abeille]

Just to follow up on this, here is a typical stack trace for 
FileNotFoundException:

04/28 09:17:55 (Warning) SZIndexer.indexObjectWithValues: 
java.io.FileNotFoundException: _2o.prx (Too many open files)

And here is what I'm doing in the flush method:

        private void flush() throws IOException
        {
                if ( ( _ramDirectory != null ) &&
                        ( _ramDirectory.list() != null ) &&
                        ( _ramDirectory.list().length > 0 ) &&
                        ( _ramWriter != null ) )
                {
                        _ramWriter.optimize();
                        _ramWriter.close();
                
                        this.writer().addIndexes( new Directory[] { _ramDirectory } );
                        
                        _ramWriter = null;
                        _ramDirectory = null;
                        
                        _reader = null;
                        _searcher = null;
                }
        }


Any insight more than welcome.

Thanks.
