I am trying to configure my Ubuntu 12.04 VPS (OpenVZ) to reboot when it runs out of memory. To do this I have added following lines to my "/etc/sysctl.conf" file.
vm.panic_on_oom = 1 kernel.panic = 14
But when I run the configuration using the command "sudo sysctl -p" I get following errors.
error: permission denied on key 'vm.panic_on_oom' error: permission denied on key 'kernel.panic'
I have tried running the same command as root and found the same error.
Can anyone please point out what am I doing wrong? or how can I fix this?
Thanks in advance.
