proc_pid_oom_score(5) File Formats Manual proc_pid_oom_score(5)
/proc/pid/oom_score - OOM-killer score
/proc/pid/oom_score (since Linux 2.6.11)
This file displays the current score that the kernel gives
to this process for the purpose of selecting a process for
the OOM-killer. A higher score means that the process is
more likely to be selected by the OOM-killer. The basis
for this score is the amount of memory used by the
process, with increases (+) or decreases (-) for factors
including:
• whether the process is privileged (-).
Before Linux 2.6.36 the following factors were also used
in the calculation of oom_score:
• whether the process creates a lot of children using
fork(2) (+);
• whether the process has been running a long time, or
has used a lot of CPU time (-);
• whether the process has a low nice value (i.e., > 0)
(+); and
• whether the process is making direct hardware access
(-).
The oom_score also reflects the adjustment specified by
the oom_score_adj or oom_adj setting for the process.
