### Goals
Since yesterday, we have been seeing a large number of crashes from FBSDKAEMManager in our app, which we last updated a few weeks ago. The crashes seem to happen immediately after the app is launched or returns to the foreground. Many users are only experiencing the crash one time, but some are getting it more than once. Strangely, the crash only seems to be happening in one of our apps, when we have several apps with a lot of shared code that use Facebook the same way. I'm wondering if this could be a Facebook server config issue like we've seen in the past causing crashes on launch. Here is the crash log:
