Yes Vinod, I was asking this question sometime back, and I got back to resolve the issue again.
I tried to see if the OOM is killing but it is not. I have checked the free swap space on my box while my test is going on, but it doesn't seem to be the issue. Also, I have verified if OOM score is going high for any of these process because that is when OOM killer kills them, but they are not going high too.
