disable core dumps on Linux systems

[rezeropoint]

ulimit -c 0

Prevent "core. *" files from occupying the entire hard drive and causing game saves to be lost

Hi @rezeropoint I myself have not run into the issue of core dumps preventing from my game from saving. Are you sure you have enough disk space free, and when are these core dumps being generated?

Hi @rezeropoint I myself have not run into the issue of core dumps preventing from my game from saving. Are you sure you have enough disk space free, and when are these core dumps being generated?

When the memory usage is 100%, the CPU will urgently reclaim memory, and the usage rate will also increase to 100%. At this point, a core dump will occur. The size of the core dump is generally several GB. When the disk space is occupied by 100% (usually 60GB~100GB for cloud servers), the archive will be lost. Running the "ulimit - c 0" command can disable the core dump function of the system/container.

@rezeropoint I've decided not to implemented in the base image. For the simple reason that it can be disabled via docker run or docker compose. docker run:

docker run -d \
    --name palworld-server \
    -p 8211:8211/udp \
    -p 27015:27015/udp \
    -v ./palworld:/palworld/ \

    -e PGID=1000 \
