UnableToOpenPixelCache on iOS 8

Hi all,
I have implemented an image processing pipeline based on imagemagick, using the C API for iOS.
One of the steps is a montage command. It consumes a lot of memory. In order to avoid memory crashes, I have had to use the "-synchronize -limit memory 5MB" options. This was working very well on iOS 7, but when I have upgraded to iOS 8 I'm getting the following error:

Code: Select all

"UnableToOpenPixelCache `/var/mobile/Containers/Data/Application/72BC713E-B6A0-4E19-93EC-DB4C40C7C50A/Library/Caches/TextureCache/panel0flipped11.jpg': Operation not permitted @ error/cache.c/OpenPixelCache/3683"

I don't know for sure, but it could be related with the fact that the file system layout of app containers has changed on disk on iOS8.

Is there anyone experiencing these issues, or have some idea on how could I solve them?

Thanks,
