Task orphaned for request in react-native – what does it mean?

It may have something to do with the way you are rendering. Your request seems to get stuck. It looks like this is the code where the error is thrown in RN (from RCTImageLoader.m):

// Remove completed tasks
for (RCTNetworkTask *task in _pendingTasks.reverseObjectEnumerator) {
  switch (task.status) {
    case RCTNetworkTaskFinished:
      [_pendingTasks removeObject:task];
      _activeTasks--;
      break;
    case RCTNetworkTaskPending:
      break;
    case RCTNetworkTaskInProgress:
      // Check task isn't "stuck"
      if (task.requestToken == nil) {
        RCTLogWarn(@"Task orphaned for request %@", task.request);
        [_pendingTasks removeObject:task];
        _activeTasks--;
        [task cancel];
      }
      break;
  }
}

I'm not exactly sure how to solve this, but a couple ideas to help you debug:

1. The <Image> component has some functions and callbacks that you could utilize to try to further track down the issue (onLoad, onLoadEnd, onLoadStart, onError, onProgress). The last two are iOS only but you could see if any of those are called to see where in the process things get hung up.

2. Alternatively, the way I would do this would be to use a ListView and place the image urls in the datasource prop for the ListView (utilizing the _.chunk method to group them as you already do). This would be a little cleaner way of rendering them IMO
