Failed to start remote desktop service VNC? Reasons are here !
Sometimes it may be necessary to disable OOM killer due to problems with it. In this case, just put the following code in /etc/sysctl.conf
vm.overcommit_memory = 2 vm.overcommit_kbytes = 0
We recommend that servers with low RAM (less than 4 GB) do not disable this function at all, as your server may have major problems.
