Hello
Sometimes the Adobe Viewer, or a custom Viewer, appears to crash. However, the iOS is in fact shutting it down because of a low memory state. You can confirm whether you have this issue by syncing an affected iPad to a Mac. Then retrieve the logs to see if there are LowMemory-[time stamp].log files. Here is where such log files, as well as crash log files, is found:
Users/[user name]/Library/Logs/CrashReporter/MobileDevice/[device name]
Look for a LowMemory log file with a time stamp that corresponds to the application's exit. Open it in a text editor and look for a line like the following:
viewer <42d0b24207f7d625b2fefef7549afce3> 33490 (jettisoned) (active)
The numbers can vary. However, if the line indicates that the "viewer" process was "jettisoned" while "active," the OS closed the process because of a low memory state. The most likely reason for this is that your viewer is reading into memory images that are larger than 1024 x 1024. Apple recommends against applications loading any image larger than this size as it contributes to a low memory state on the device. It can result in what appear to be application crashes. Review your folio source files and ensure that no images of greater size are used. If they are, simply resample them, and republish your content.
The low memory state can also be the result of having too many applications running at once. Shut down applications you are not actively using to free up more memory.
How to free up memory on your iPad
1. From the home screen, double-click the Home button to display recently used applications.
2. Tap and hold one of the applications until a red minus appears above it.
3. Tap the red minus for all apps that are not currently needed.
4. Tap anywhere above the list of recently used apps, to return to the home screen.
