NAME
/proc/pid/oom_score - OO-killer scoreDESCRIPTION
- /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 OO-killer.
A higher score means that the process is more likely to be
selected by the OO-killer.
The basis for this score is the amount of memory used by the process,
with increases (+) or decreases (-) for factors including:
-
- [bu]
- whether the process is privileged (-).
-
-
Before Linux 2.6.36
the following factors were also used in the calculation of oom_score:
-
- [bu]
- whether the process creates a lot of children using fork(2) (+);
- [bu]
- whether the process has been running a long time, or has used a lot of CPU time (-);
- [bu]
- whether the process has a low nice value (i.e., > 0) (+); and
- [bu]
- 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.
