I've implemented a `node-red-node-mongodb` node set into my flow, essentially managing a user base and related data,

I've had a few times where the MongoDB server goes off line with connection issues.

I look at the `mongodb.log` file and see entries like this:

`connection accepted from 127.0.0.1:58660 #1137 (1118 connections now open)`  
` [listener] pthread_create failed: Resource temporarily unavailable`

I suspect this is creating an instance each time I connect and not closing them... fast enough?

How can I ensure this will be stable and efficient in the future? I'm on a small AWS instance, for now... Not sure if this has anything to do with the accumulation of instances on the mongodb end of things?

The end goal is to have a growing set of users, and related content for the site, all via node-red, with a scaleable mongo set... The payloads are minimal, containing some user ID info, and some privileges... Same with the other DB's being utilized.
