memory-leaks

Hello,

I have the following code in a loop iterating over the different document objects:

NSAutoreleasePool* pool = [[NSAutoreleasePool alloc] init];
[document primitiveValueForKey:@"data"];
[data writeToFile:filename atomically:NO];
[document.managedObjectContext refreshObject:document mergeChanges:NO];
[pool release];

The "data" property is a large blob (a 1MB image). And as I monitor the memory with the Allocation Instrument memory usage is increasing. I cannot find where the leak is coming from and how to remove it.

Thanks!

I'm a complete newbie when it comes to iOS programming and much less Core Data.
