Node 7.7.2 MongoDB error

[dnohr]

I'm not sure if it's PM2 or a MongoDB driver bug. After upgrading to Node 7.7.2, my applications connected to MongoDB failed with following error. I have full connection from my server to the database.

NODE: 7.7.2
PM2: 2.4.2
MongoDB: 2.2.24

Solution:
After downgrading to Node 7.7.1, my applications through PM2 was able to connect to the DB again.

Just a heads up before upgrading your environment to the latest node release.

Thanks.

We will push an update today to avoid this with pm2, still opened an issue over the responsible module : othiym23/async-listener#99
Thanks for reporting this !

@vmarchaud @dnohr actually, it's bug on Node 7.7.2 and will be fixed by nodejs/node#11762

[dnohr]

@vhain Sounds good, thanks for the details.

The same problem!

We released pmx 1.0.4 that should fix this issue
