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.
