Zombie processes left after each git command which interacts with remote repo

[bitme345]

git commands which require interaction with remote repo leaves zombie proceses. 1 process per each git command.

docker exec -it repro ps -o pid,ppid,stat,tty,args

PID   PPID  STAT TT     COMMAND
    1     0 S    ?      npm start
   18     1 S    ?      {MainThread} node dist/index.js
   39     1 Z    ?      [git]
   45     1 Z    ?      [git]
   57     1 Z    ?      [git]
   63     1 Z    ?      [git]
  154     0 R    136,0  ps -o pid,ppid,stat,tty,args

Minimal reproducible example

Observed when running in node:24-alpine docker image
Does not happen in MacOS

simple-git version 3.28.0

I can confirm this issue is also present on my machine, when using node:20-alpine docker image.

For anyone interested in a temporary fix, migrating your docker image from an alpine linux image to a debian one should fix the issue.

As for the bug it might not be that useful but i found out the following details :

• Read commands will generate only 1 zombie no matter how many time they are executed.
• Write commands will generate n zombies depending on how many n the write command is executed.
