[Bug]: MongoDB connection error throw randomly

[shiipou]

What happened?

Sometimes, there a mongodb connection error that got thrown randomly when accessing Lenra server using app.lenra.io
We got that error multiple times a day, but not every days.

Mostly always thrown after this error :

auth failed for user root: Authentication failed. 18

We need to check mongo logs before going futher.

What browsers are you seeing the problem on?

Might be a connection pool configuration problem.
