Npm install with alot of private repositories - connection_closed, cb never called()


What I Wanted to Do

I am using a package.json with 18 private packages (all pointing to my gitlab, “git+ssh” …). I Want to run npm install to download my packages.

What Happened Instead

When I try to run npm install, depending on npm version, I get different errors like ’ remote host connection_closed’, cb never called() etc…

Reproduction Steps

It seems it happens when you are requesting a server with sshd allowing less connections than npm install does when using mode silly to get metadata about the repositories.

My server had 10 connections max ( ).

So to reproduce it should be easy, but requires to setup an environmnent:


By increasing sshd_config MaxStartups to 30 on my server hosting Gitlab, I don’t have the error anymore.

I think that in silly mode, npm doesn’t close ssh connections, and is stacking them until it has all the repositories information.
