To list the processes sorted by the memory usage 

ps --sort -rss -eo pid,pmem,rss,vsz,comm

More information here : how-to-detect-a-memory-leak

The server is killing processes to free memory, this is what happens when all the virtual pages are allocated (swap+ram). If possible the best would be to restart the server to have all the stopped services restarted and and memory free.

More information here : Debug out-of-memory with /var/log/messages

Edit:

May  8 03:53:21 bwnet kernel: [5088999.370529] Free swap  = 0kB
May  8 03:53:21 bwnet kernel: [5088999.370530] Total swap = 0kB

Reading your logs it seems that you have no swap. You may allocate some, that will allows you to manage the problem before it becomes critical.

enter image description here

  • Install htop via sudo apt install htop
  • start htop by typing htop
  • Press F6 to trigger the sort-function and select MEM% on the left side via arrow keys

As a result you get a dynamic list of all processes sorted by mem-usage
