We have been facing a weird crash from core data from long time and haven't found anything what to do. Below is the crash stack to get more insight on it. It is a production issue and not replicate at our end.

Looks like the problem could be in NSManagedObjectContext performing some work. Maybe integrating some data-collection lib, as Crashlytics can help.

Regarding stack trace: could you please send the original error message (as shown on screenshot)?sample stack trace.

For now I can draw only bare suggestions that are not so relevant.
