Description

What's going wrong?

Currently, PM2 lacks support for multiple users on Windows. This is due to the IPC pipe names being hardcoded in:

https://github.com/Unitech/pm2/blob/5e708459aca32903fd363230e24c37b3e38bb48d/paths.js#L82-L88

How could we reproduce this issue?

Run PM2 as two different users on Windows.

Supporting information

Operating system: Microsoft Windows Server 2012.

Research direction

Start with paths.js lines 82-88, where the Windows IPC pipe names are hardcoded, and inspect how the PM2 daemon and clients derive those names. Reproduce the failure by running PM2 as two Windows users; done means both users can run and connect to their own PM2 daemons without the EPERM pipe error.
