I included crashlytics in my ios app and distributed it via enterprise. Crashlytics keeps on reporting below crash daily regarding Reachability. I googled, but didn't get what causing this crash.

It looks like you're registering a reachability observer which is being deallocated but not removing itself as an observer before that happens. So, when the reachability notification is posted later it is sent to a deallocated instance (i.e. random memory location) and you get a crash.
All observers (whether of reachability or any other notification with NSNotificationCenter) should remove themselves as an observer before they are deallocated.

Can anyone please suggest me what can be the issue?
This kind of NSInvalidArgumentException, especially because it's on a private class, is probably due to a Zombie object. You are sending a message "setCursorPosition:" to an object that no longer exist, but another one is in it's place. In this case "_NSObserverList".
Try running with the "Zombie Objects" diagnostics objects to trace down which is the object that should receive that message but was gone. That option keeps the objects in memory when they are released, but marked as zombies.
I got a crash from Fabric,the stack is below:

I don't know why it would be _Block_release after (anonymous namespace)::AutoreleasePoolPage::pop(void*). Is it possible that a block was added to autoreleasepool?if possible, why the block crashed at release and it not crashed at invoke?
Ok，I had resolve this bug.The reason for the crash was that I had hook the function objectAtIndex for NSMutableArray.And If user switch from background,the app would get a crash -[UIKeyboardLayoutStar release]: message sent to deallocated.
So remove the hook code will resolve this bug.

terminate called after throwing an instance of 'NSException'
Program received signal: “SIGABRT”.
Hard to say given just the stack trace, but I would suggest the following:
Implement applicationWillResignActive: in your UIApplicationDelegate to ensure that video playback is paused or stopped before the application enters the background.
Create a custom UIApplication subclass to use in your app, and override the _handleApplicationSuspend:eventInfo: method so that it returns without propagating the event to other classes further down the chain.
Figure out how to unregister your MPMoviePlayerViewController component from the notification center so that it does not receive the 'ApplicationDidEnterBackgroundNotification'.
Can anyone help me make sense of the crash log below? It came from Apple after inquiring further about a crash my app had. They rejected the app because of this crash, but I have never once been able to make it occur on my end or with 10+ beta testers. So basically, it is only occurring for them for some reason. It looks like it has to do with presenting a view, but that's weird because, like I said, this view is coming up perfectly fine.

This had to do with forgetting to add some required built variables to my project that the Three20 libraries use. I didn't notice it because you can't run App Store release builds locally.
