Status in linux package in Ubuntu: Incomplete Bug description: On Ubuntu 16.04 LTS and the newest kernel 4.4.0-157, I tried the following command: echo "vm.overcommit_memory = 2" >> /etc/sysctl.conf echo "vm.overcommit_kbytes = 0" >> /etc/sysctl.conf sysctl -p Then I can't reboot, all the commands are invalid, the system explodes. After a forced restart, I can't even connect it with ssh. #reboot reboot -bash: fork: Cannot allocate memory After some searching and inspection, I find the default value of vm.overcommit_kbytes is 0, so why set it to 0 again will get such a result?
