[fw-general] Fatal error: Uncaught exception 'Zend_Search_Lucene_Exception' with message 'rename(./system/search/my-index/segments.new,./system/search/my-index/segments)

Hi,
I am trying to implement Zend_Search_Lucene on our site.
I am trying to create the index like this.
     function updateAction(){
         set_time_limit(0);
         $index = Zend_Search_Lucene::create('./system/search/my-index');
         $products = new Products();
         $productsRS = $products->fetchAll();
         foreach($productsRS as $product){
           $doc = new Zend_Search_Lucene_Document();
           
$doc->addField(Zend_Search_Lucene_Field::Keyword('productTitle',$product->productTitle));
           $index->addDocument($doc);
         }
         $index->commit();
     }
but usually I get
Fatal error: Uncaught exception 'Zend_Search_Lucene_Exception' with 
message 
'rename(./system/search/my-index/segments.new,./system/search/my-index/segments) 

message. Once I just refreshed and it created the index without further 
error. I managed to browse the index using Luke.

"my-index" directory.
