When I analyse a app memory problem, I found its maps (cat /proc/pid/maps) like this: 

 903 5fec1000-5fec2000 r--s 00001000 b3:10 98         /system/app/PacProcessor.apk

 904 5fec2000-5fec3000 r--s 00000000 b3:10 98         /system/app/PacProcessor.apk

 905 5fec3000-5fed7000 r--s 00560000 b3:10 125        /system/app/iReader.apk

 906 5fed7000-5ff09000 r--s 0019a000 b3:10 125        /system/app/iReader.apk

 907 5ff09000-5ff0b000 r--s 00043000 b3:10 81         /system/app/Galaxy4.apk

 908 5ff0b000-5ff0c000 r--s 00042000 b3:10 81         /system/app/Galaxy4.apk

It seems this app loads other app's code into its stack.

How can I avoid this kind memory allocation ?

  • what is the process name? if it's a system process, then it is unavoidable. I guess you have to kill the apps themselves to release those resources. – mariusm Aug 28 '14 at 13:13
  • yeah,it's a system app(not persistent,but installed at /system/app),but i checked other apps in /system/app dir,they don't have these allocation. – summer Aug 29 '14 at 03:35

From proc manual on Linux:

 /proc/[pid]/maps
          A file containing the currently mapped memory regions and  their  access  permissions.   See
          mmap(2) for some further information about memory mappings.
