Correcting a rather significant typo: setting the oom_score_adj for programs as high as 1000 should be -1000 to be left alone. 1000 would make it a prime candidate for an OOM kill. Positive integers should be used on sacrificial superfluous programs. [1] As an example OpenSSH sets the sshd to -1000 by default.
