The prompt that you see means that the JIT is not able to use the native stack and stack pointer for Erlang processes. That will slightly reduce performance and perfwill not be able to show any information about Erlang functions. You will still get most of performance improvements of the JIT compared to not using the JIT.
The reason that the native stack is not used is that Alpine uses the musl C library which don’t support safely switching stacks when handling signals.
If you really need the native-stack support in Docker, it should work if you use another Linux distribution that uses glibc, for example Ubuntu.
