Linux dedi Crashing Unexpectedly

Here is another log from yesterday. 
sdtdserver-console-2023-06-16-213001.log

I had the same problem with α20, but the problem was solved by adjusting to linux.

1.Check kernel parameter
cat /proc/sys/vm/max_map_count
I think the standard value for Ubuntu20 and 22 is about 65530, but I think that 7dtd reaches the limit around 8-10GB of memory usage and the s
erver crashes.

2.set new parameter
Add the following lines to the end of /etc/sysctl.conf.
vm.max_map_count=262144

If you have more than 32GB of memory, the following settings may be good to deal with abnormal memory consumption of α21.
vm.max_map_count=524288

3.Apply setting
with root privileges
sysctl -p
or
machine reboot

I don't know how 7dtd uses memory, so the parameter values are my rule of thumb.
If you find better tuning, please share.

I wouldn't be keen to do that since if 7 Days does need to use enough memory to make this change effective, making this change will reduce the performance of the server when it is expanding the RAM to that extent. 

 

Curiously, this hasn't happened much at all in the past couple of weeks. We have not made any changes in our setup though.
