NAME
/proc/pid/oom_score - OOM-killer score
DESCRIPTION
/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 de-
creases (-) 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.
