Pm2: TypeError: Buffer.alloc is not a function

[FrancoisPala]

What's going wrong?

When starting my Docker container that is using pm2, I get this error:

pm2 launched in no-daemon mode (you can add DEBUG="*" env variable to get more messages)

How could we reproduce this issue?

Start a Docker container that uses pm2

Supporting information

We published pm2 version 3.0.2 that pin the version of pidusage and should fix the issue, can everyone confirm that it's good now ?

Switched back to 2.10.4 for now, will try the newer version soon. Thanks! :)
