Erlang > 19 stopped working on mac

I used to use erlang/elixir installed by homebrew and kiex on my mac. But couple of days ago it stoped working. I tried uninstall everything and install it again. It didn’t help. Right now I tried asdf and same issue. Erlang 19 is working but everything newer not. It start, show something in console but that’s it, it’s only start consuming memory and cpu, it takes about 12-20 GB of memory and 120 % cpu. Any ideax what can be wrong please?

asdf install erlang

Erlang has been installed. Activate globally with:

    asdf global erlang

Activate locally in the current folder with:

    asdf local erlang

➜  ~ asdf global erlang

Erlang/OTP 20 [erts-] [source] [64-bit] [smp:8:8] [ds:8:8:10] [async-threads:10] [hipe] [kernel-poll:false]

As a start, make sure to run this in your console, just in case:

xcode-select --install

And then retry installing Erlang through asdf.

Thanks, I already did so:

xcode-select: error: command line tools are already installed, use "Software Update" to install updates

and I opened XCode just to be sure everything is ok, because sometimes it finish installation after you open it.

Then I’m not really sure. Have you tried 21? And 22.0.1 in particular?

Yes, only 19.x works and elixir 1.8 need > 20

I created new user and I installed erlang and elixir with asdf and it works. So I have to have something wrong with my user’s “namespace”. Maybe zsh has some wrong setup.

I removed this line from .zshrc file and it works
export ERL_AFLAGS="-kernel shell_history enabled"


Hmm, I wonder why, I still have those in my shell environment…

In the elixir-lang slack I already suggested that the history file might be broken, @quatermain didn’t report back their though.

Hmm, do you have a link to a BEAM bug report about this?

No, I wanted to check first with @quatermain if moving the history file away would help before filing/searching a bug report.

Hi guys, sorry for delay. I’m pretty sure it’s problem with history, but I can not find where is that history file. Can you navigate me please?
When I turn off that flag it works, when I turn on, erlang doesn’t work. Even without recompiling. So it has to be problem with that history “file”

Default place seems to be ~/.cache/erlang-history.

If you backup and delete that folder, does it work with that flags enabled?

Keeping the faulty history might be beneficial for a potential bug report.

but problem is that I don’t have that file :upside_down_face:
I tried this:
sudo find / -type f -name "erlang-history"
and not results.

It is a directory, and I was very explicit with the path…

~/.cache/erlang-history should be available. ls -ld ~/.cache/erlang-history.

Well, unless erlang does use the XDG environment vars to alter the location and it is put somewhere else for that reason, but then you should still be able to find it using -type d for find.

Found it.

I moved all files inside, allowed history and it works. So problem is with these files.

So you have not backed them up for introspection?

yes, I have it. is it save to upload here or? not sure what is inside

I’m not sure as well. But they will probably contain major parts of your erlang and elixir shell history and if you are in doubt even might contain passwords you used as function arguments.

@bjorng, @rvirding do you know more, or if there is already something known that malformed/corrupted histories can cause the erl to allocate a lot of memory while consuming a lot of CPU?
