Is your code on github or public so that I could use it for debugging?

Hello Jhon Honce!

After many days trying to do the application works, I decided to remove it and to create a new cartridge scalable. This new cartridge I added the same application and it is working, no problem or error appeared in relation to MongoDB connection.

It was a surprise to me and I don't know to say what may have gone wrong in the first attempt.

Please reopen if you have another occurrence.

Sorry for the inconvenience.
