Everething that allows to save data can simply fail by the same scenarios. In some cases this can be 50mb of free space. In some cases - it's 400mb.
This must be fixed. Please check iOS Adobe AIR sources that working with file saving. External API for this - FileStream and SharedObject.
Here is two different opened bug tickes:

P.S. As I'm a little bit know how this works at native side - there is some issues because using Objective-C app can go do this limit. Also checking of free space will not solve this issue. You will see that freespace is available. But you can't write to it from the AIR. Native APP - can do this.
