Unity is now restarted, the site is available, screenshot in the deposit.Oom-killer operations talk about a problem with a lack of operational memory.If this problem will be repeated, you can increase the volume of the VPS server operating memory in the settings to solve the problem.You can also add tasks to check the state of the final process and reboot it in case of its forced completion or protect the process from OOM Killer in the way described in this article: http://geckich.blogspot.com/2013/12/linux-out- of-memory-killer-oom.html
If high memory consumption occurs in a short time, you can create a swap file or increase its size.I will note that the swap has a lower speed compared to the operating memory and is not suitable for cases where the application speed is required (e.g. for a web server or database server)
