Getting lib_uv_open error when trying to use cluster package

[alex-lange]

Hi!

I am playing around with abstract sockets with our node server, and one issue I'm running into is getting it to work with the cluster library. It appears that when the workers try to connect, I get the following error:

Error: EEXIST: file already exists, uv_pipe_open

I see that you contribute to libuv so maybe this will make sense to you. I am using node version 12.16.1.

The cluster code works when not using the cluster package, and also when using the cluster package with regular unix domain sockets.

I have encountered the same issue. Did you find a way to work around? @alex-lange

The error was returned from
