What are all the possible conditions for oom process to kick in?

hello there,
NOTE: It is the task of the OOM Killer to continue killing processes until enough memory is freed for the smooth functioning of the rest of the process that the Kernel is attempting to run.
The OOM Killer has to select the bestprocess(es) to kill. Best here refers to that process which will free up the maximum memory upon killing and is also the least important to the system.
The primary goal is to kill the least number of processes that minimizes the damage done and at the same time maximizing the amount of memory freed.
To facilitate this, the kernel maintains anoom_score for each of the processes. You can see the oom_score of each of the processes in the /proc filesystem under the pid directory.
$ cat /proc/10292/oom_score
The higher the value of oom_score of any process, the higher is its likelihood of getting killed by the OOM Killer in an out-of-memory situation.
hope it help you!
