| # Out-of-memory killer adjustments file. |
| # Applied by /etc/init.d/vz script on start. |
| # One can apply it any time by running: |
| # |
| # cat /etc/vz/oom-groups.conf > /proc/vz/oom_score_adj |
| # |
| # Format of the file is four space-separated fields: |
| # |
| # command parent uid_filter adj |
| # |
| # 1 command |
| # A mask for matching the task command name. |
| # "foo" matches only "foo", "foo*" matches "foo" and "foobar", |
| # "*" matches any string. |
| # |
| # 2 parent |
| # A mask for parent task command name. |
| # |
| # 3 uid_filter |
| # Task uid filter: |
| # -1 match any task_uid |
| # >= 0 exact match (task_uid == oom_uid) |
| # < -1 match lower uids (task_uid < -oom_uid) |
| # |
| # 4 adj |
| # OOM-score adjustment, a number from -1000 to 1000. |
| # A positive number increases the chances of killing, |
| # while a negative number decreases it (more protection). |
| # -1000 makes a process unkillable till any other process exists. |
| # |
| # Example: |
| # sshd init -500 -100 |
| # A process with the name of sshd, a child of init, with uid < 500, |
| # can use 100 promille (10%) of container's memory without being killed |
| # |
| # NOTE that new distros adjust from inside the CT for important |
| # services, so this setup is only needed for old distros which are not |
| # OOM score adjustment aware. |
