Dear All,
I am running a simple test program that just do malloc and memset. The
testprogram is run using below attached script
while true
do
./stress &
./stress &
./stress &
./stress &
sleep 1
done
we got this issue on embedded Target.
After analysis we found that most of task(stress_application) is in D
for uninterruptible sleep.
application state
stress x
stress D
stress x
stress D
stress x
stress D
stress x
sleep D
So I observe after 10-15 min Kernel crash with
Kernel panic - not syncing: Out of memory and no killable processes...
I am attaching Kernel Crash log + Test application.
Thanks
