# echo -15 > /proc/$PID/oom_adj $PID is the process ID. You can set valid ranges for oom_adj from -16 to +15, and a setting of -17 exempts a process entirely from the OOM killer. The following command exempts X from the OOM killer. # pgrep -f "/usr/bin/X" | while read PID; do echo -17 > /proc/$PID/oom_adj; done |
