Describe the problem

After running zenbot for about 5 or so minutes, it throws an error. Seems to be an issue with the mongo module, after researching and looking at the error.

This also seems to happen when the bot does a sell.

[theposs101]

Seems that updating the mongojs module fixes it

Just got the error again, reopening.

Managed to fix it by downgrading to Ubuntu 16.04. I've had it run for 24 hours without issue. It might be an issue related to MongoDB and/or NodeJS's MongoJS module on Ubuntu 18.04. Thanks!

Same issue.
mongodb server v3.6.5
mongodb module v3.0.10
nodejs v10.2.1

@PossibilitiesMC What MongoDB version you have now?
