I have an application which is dealing with many data structures, uiimageviews, videos, creating bit map context and so on. Every time the application is crashing on its continuous usage for a long time. The application is crashing with the memory warning --> Application exited abnormally with signal 9. What may be its reason. What does signal 9 means.
The "terminated due to signal 9" message just means your app was terminated by a SIGKILL signal.
signal 9 is SIGKILL this is use to kill the application. though we can also mask some of the signals but not all signals can be masked in an application.
Cause 1 - Memory LeaksBecause the PermGen has a finite size, reloading the flawed application just a handful of times can trigger an OutOfMemoryError, or OOME. Eliminating retained references to the web application class loader will allow Garbage Collection to function properly, preventing these errors.
I think this is due to the memory issue. Your app is using lot of memory due that is app is killed..
