ram limitation usage

for some reason the docker image don't use more than 2GB of ram, I tried everything, but when it uses 2GB the server can't render new dimensions or new chunks, i have 24gb of ram on oracle, 5 vm.standard.a1 flex, performance isn't an issue, but the ram usage i simple can't understand, can someone help?

docker inspects returns the following:

Start by examining the reported Docker configuration, especially HostConfig.Memory and MemorySwap from the docker inspect output, then reproduce the server behavior when it reaches roughly 2GB while rendering new dimensions or chunks. Done means identifying why the container or Bedrock server stops using available RAM and documenting or implementing a verified resolution.
