Hi! I’m still getting zombie processes with erlexec and nothing that I do seems to be able to resolve this. Firstly, i’m on linux. Secondly, i can’t use muontrap, since I need to stream input and output into the other process.
Here’s the code:
#... Genserver Headers
def init(_) do
:erlexec.run_link("priv/forever.sh", [:stderr, :stdout, :kill_group])
#...
forever.sh
#!/bin/bash
while true; do
sleep 1
end
Control-c/a definitely creates a zombie (I think the GenServer doesn’t even get the stop message), and even System.stop(0) creates a zombie.
I’m free to put anything in the top of the forever script, so if I can use that to, maybe set the process group or a job, I can definitely do that, but I’m not familiar enough with linux to know if that makes sense. thanks
Thanks in advance.

Not sure if
rambocould help there as I think it does the same thing as muontrap, but maybe worth checking.LostKobrakai
You can also take look at ex_cmd.

There is no clean way to do it without using middleware if you are consuming
stdin. You need another OS process which act likemonitorand do the cleanup.mountrap&ExCmdare such middlewere, but mountrap does not support communicating with the external process and ex_cmd does.Also If you are streaming a lot of data in/out of beam then it can lead to memory issue. ex_cmd also solves that. See memory issue mentioned here

sadly none of the above solutions worked. I was able to get a solution I was okay with:
:os.getpid()to get the os pid of the erlang process.
