hi 

oom-killer is invoked when we are rendering our texture, log as below:

scenario details:
1.process name: zadas_ui, for rendering widget in different mode. 
2. enable diff modes sequentially by click.
3.if loading increases, The process oom, and file-rss value: 140M, but mem has more than 200M left
 
when app widgets first create, following egl aps will be invoked,  glGenTextures-> glBindTexture -> glTexImage2D->glDrawArrays
for widgets texture will not be destoryde for the app whole  lifecycle.
 
our zadas_ui app in user space will ask for allocation to render Texture. As attached log in (https://e2e.ti.com/support/processors/f/791/t/971834?tisearch=e2e-quicksearch&keymatch=oom), there are so much page allocated error logs, when egl create fence sync error occurred. does the remaining mem which mapping to V ram is lower than threshold?
 
and we try echo 1 >> drop_caches , oom still happened
 
this is omm-meminfo log oom_meminfo.xlsx

    Hello,

    Sorry for the delayed follow up. Are you still using this issue?

    We seem to be clearly running out of memory (failure in alloc_pages). Please note that the GPU cannot use memory in highmem.

    Does this happen over a period of time? Have you looked to see if available memory decreases? Wondering if there is a leak in system.

    Regards

    Hemant
