IPad Core Data Leak ?
Im using XCode 3.2.3 and have created an app using the SplitView template with Core Data.
When i run the default app on the device (3.2) in debug mode with instruments running
i am seeing a leak.
When the default app has no items added to the table view within the split view there is no leak.
But after adding items and running the app a leak is reported.

Responsible Frames are ....

NSPushAutoreleasePool
+[NSThread currentThread]
WTF:initializeMainThreadPlatform()
WTF:initializeMainThreadPlatform()
WTF:initializeMainThreadPlatform()

I beleive the issue happens when fetchedResultsController is called 


    - (NSFetchedResultsController *)fetchedResultsController {
    
    if (fetchedResultsController != nil) {
        return fetchedResultsController;
    }
    
    /*
     Set up the fetched results controller.
     */
    // Create the fetch request for the entity.
    NSFetchRequest *fetchRequest = [[NSFetchRequest alloc] init];
    // Edit the entity name as appropriate.
    NSEntityDescription *entity = [NSEntityDescription entityForName:@"Event" inManagedObjectContext:managedObjectContext];
    [fetchRequest setEntity:entity];
    
    // Set the batch size to a suitable number.
    [fetchRequest setFetchBatchSize:20];
    
    // Edit the sort key as appropriate.
    NSSortDescriptor *sortDescriptor = [[NSSortDescriptor alloc] initWithKey:@"timeStamp" ascending:NO];
    NSArray *sortDescriptors = [[NSArray alloc] initWithObjects:sortDescriptor, nil];
    
    [fetchRequest setSortDescriptors:sortDescriptors];
    
    // Edit the section name key path and cache name if appropriate.
    // nil for section name key path means "no sections".
    NSFetchedResultsController *aFetchedResultsController = [[NSFetchedResultsController alloc] initWithFetchRequest:fetchRequest managedObjectContext:managedObjectContext sectionNameKeyPath:nil cacheName:@"Root"];
    aFetchedResultsController.delegate = self;
    self.fetchedResultsController = aFetchedResultsController;
    
    [aFetchedResultsController release];
    [fetchRequest release];
    [sortDescriptor release];
    [sortDescriptors release];
    
    return fetchedResultsController;
}    


Any advice or pointers appreciated.
