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 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.
