Version: Latest (2.6.2)
Hardware Raspberry Pi 3B (1GB RAM)
So far this happened 3 times. NPM works perfectly for a few hours and then suddenly dies while all other containers keep running fine. SS from portainer:

The error I see is Exited with 137
Inspect:

Logs (don't show any errors - crash happened at 6:29AM, nothing at that moment):

I suspect that my RPi might be running OOM? But last I checked htop the RAM was at 600MB/1GB so quite far from full. Any ideas?
PS: I have put Restart Policy as Always in order to alleviate this...
