POSIX error 12 (“Cannot allocate memory”) while uploading files from an iPhone

Question

I\'m working on an iPhone application that involves uploading full photos from the camera (generally between 1.5 to 2.0 MB each) as well as their thumbnails (much smaller) to Am

Have resolved this error with using operation for request (NSMutableUrlConnection) with @autorelease{} for main function. NSPOXIS appears only sometimes.

- (void)main
 NSURLConnection* connection;
    @autoreleasepool //urgently needed for 3G upload
    {

        self.currentRequest = [[NSMutableURLRequest alloc] initWithURL:[NSURL URLWithString:@"test.php"]];
        [self.currentRequest setHTTPMethod:@"PUT"];

        [self.currentRequest setHTTPBody:self.data];//inpustStream doesn't work

        connection = [NSURLConnection connectionWithRequest:self.currentRequest delegate:self];
        [connection start];

    }//end autorelease pool

        do 
        {

            [[NSRunLoop currentRunLoop] runMode: NSDefaultRunLoopMode beforeDate: [NSDate distantFuture]];
            if ([self isCancelled])
            {
                connection          = nil;
                isFailed = YES;
                break;
            }
            self.status(statusUpdateMessage);
        } 
        while (!isFailed && !isCompleted);
        [timer invalidate];//test
        timer = nil;

//corresponding of status via blocks
        self.completed(!isFailed);
        self.status(isFailed ? errorMessage : @"Completed");
        if (isFailed)
        {
            self.failed(errorMessage != nil ? errorMessage : @"Undefined error");
        }

        self.data = nil;
        self.currentRequest = nil;

        connection = nil;

}
