CFNetwork / NSURLConnection leak

Question

Running instruments on the device, I intermittently incur a memory leak of exactly 3.5 KB in CFNetwork, the responsible frame being \"HostLookup_Master::HostLookup....\"

Answer 1

That 3.5kb memory leak sounds familiar, had that when dealing with threads:

@implementation MyClass
+ (void)login
{
    //MyClass *this = [[MyClass alloc] init]; // MEMORY LEAK
    MyClass *this = [[[MyClass alloc] init] autorelease];
    [NSThread detachNewThreadSelector:@selector(anotherThread)
                             toTarget:this
                           withObject:nil];
}

- (void)anotherThread {
    NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init];
    [self doStuff];
    //[self release]; // MEMORY LEAK
    [pool release];
}
@end

Every login created 3.5kb leak. Using autorelease solved the problem.

Answer 2

It seems that apple might be aware of the 3.5k leak related to CFNetwork usage and may have been reported as a bug already.
