Hi All , I am also having the same kind of issue in my recent Android project . I am getting free RAM memory values degrading as compared to other branch code which is based on 3.4.5 kernel with jelly bean , in current branch we are using kernel 3.10.17 with Kitkat , from the logs and cat/proc/meminfo we are getting diff of total 62 MB free RAM . I am suspecting there should be some memory leak happning inside kernel or native or userspace java code or any otherthing which i am not able to track ,any suggestions for this issue how to find or track that free memory usage . As far as kernel memleak is concerned i have already tested that with kmem leak option enabled and i would not found any memleak inside kernel . ANY IDEA, who consumed the rest of the RAM memory.
