When will iOS trigger the didReceiveMemoryWarning method? I am getting a crash in my app while playing an DRM encryped video. Check the below screenshot. I am using only 27mb of RAM and I am getting a memory warning in the console as you can see in the image and the app simply crashes. What can be the possible reason?

I tried profiling the app using allocation instrument. I checked the discard events with freed memory and ran the app. There also I am getting the memory warning message even though the app only uses ~50mb of RAM.Please check the image below.

IIRC, iOS broadcasts memory warning to all the apps when total free memory is low, so it may be problem caused by other apps. – user28434'mstep Oct 18 '16 at 13:13
But I don't have any other running apps in the background.In the second image attached you can see the total bytes column.It consumes only 58mb.I checked the `discard events for freed memory` .SO it would be the current amount of RAM used by the app right? – abhimuralidharan Oct 18 '16 at 13:18
check `Usage Comparison` in first screenshot. – user28434'mstep Oct 18 '16 at 13:19
Have you try to add a breakpoint to didReceiveMemoryWarning? – Ahmad F Oct 18 '16 at 13:20

@AhmadF What should I do after putting a breakpoint there? – abhimuralidharan Oct 18 '16 at 13:30
@abhi1992 is it reachable? (does the compile stops at it before crashing?) – Ahmad F Oct 18 '16 at 13:51
@AhmadF yes it is.. I can log some warning message there. – abhimuralidharan Oct 19 '16 at 07:07
