What steps will reproduce the bug?

node.js crashes randomly with this error. We can not find any way to reproduce it.

How often does it reproduce? Is there a required condition?

No response

What is the expected behavior? Why is that the expected behavior?

Additional information

I believe the error would be caused by a EAI_MAX error

FreeBSD glibc's getaddrinfo() can return a EAI_MAX error, which is not trapped by libuv uv__getaddrinfo_translate_error()

Ref:
getaddrinfo man page says it can return errors from gai_strerror(3)
Freebsd man page: https://man.freebsd.org/cgi/man.cgi?query=getaddrinfo&sektion=3
gai_strerror(3): https://man.freebsd.org/cgi/man.cgi?query=gai_strerror&sektion=3&manpath=FreeBSD+13.2-
RELEASE+and+Ports

When googling around, I can find a reference to EAI_MAX error in netdb.h.
Ref: https://gitea-dev.freebsd.org/FreeBSD/src/src/tag/release/13.1.0/include/netdb.h

In node.js' uv__getaddrinfo_translate_error(), there is a case for all errors, except EAI_MAX
That's the case for node.js 16.18.1 which we are using, but also the main branch too.

Ref: https://github.com/nodejs/node/blob/main/deps/uv/src/unix/getaddrinfo.c

Therefore, we probably need to add:
#if defined(EAI_MAX)
case EAI_MAX: return UV_EAI_MAX;
#endif

And of course UV_EAI_MAX would need to be defined.

@BenoitMercier thanks for the report. Can you confirm that the error is actually EAI_MAX or is it just a guess? If the latter, can you add a printf in uv__getaddrinfo_translate_error() so we can actually know the error?

Looks like we should have that mapping in libuv indeed.

I have no clue how to compile. I just identified EAI_MAX as the only possibility looking at uv__getaddrinfo_translate_error() and netdb.h
