i cannot find anything "interesting" in the logfiles sadly
my system has 8gb ram and it looks like as it gets maxed out by unraid and the forestserver-docker. might really be the ram.. but unraid itself does not crash/restart or something.
i did nothing special in the container, i just installed it, changed some basic settings in the config for the dedicated forest server and thats it.
im using a thinkcentre m73, pretty old mini-pc, cpu is a i5-4440 CPU which runs at ~10-25% when 3 people are connected to the forestserver. ram is as i said, maxed out if the forestserver is running (players on it, even at 1 player).
I dont know CA Backup, its a pretty fresh unraid install with only theforest-docker so far.
the crashes are random, reproducable with some time but not predictable.
