@MajorP93 you say to have 8GB Ram on XO, but it OOMkills at 5Gb Used RAM.
did you do those additionnal steps in your XO Config ?
You can increase the memory allocated to the XOA VM (from 2GB to 4GB or 8GB).
Note that simply increasing the RAM for the VM is not enough.
You must also edit the service file (/etc/systemd/system/xo-server.service)
to increase the memory allocated to the xo-server process itself.
You should leave ~512MB for the debian OS itself. Meaning if your VM has 4096MB total RAM, you should use 3584 for the memory value below.
- ExecStart=/usr/local/bin/xo-server
+ ExecStart=/usr/local/bin/node --max-old-space-size=3584 /usr/local/bin/xo-server
The last step is to refresh and restart the service:
$ systemctl daemon-reload
$ systemctl restart xo-server
