iOS 5 Core Data freeze

Question

I try to do the following simple thing:

NSArray * entities = [context executeFetchRequest:inFetchRequest error:&fetchError];

Nothing fancy.

Answer 1

This really sounds like trying to access a NSManagedObjectContext from a thread/queue other than the one that created it. As others suggested you need to look at your threading and make sure you are following Core Data's rules.
