Recently the number of connections have skyrocketed. The useUnifiedTopology: true setting seems to be causing new connections on existing warm containers. I.e. the connection is lost, even after just 5 seconds if no activity, for the same warm container.
If I set useUnifiedTopology to false, the issue goes away, however new connections sometimes time out.
Sorry to hear that you’re suddenly having connection issues. We’d love to help in the context of your Atlas cluster. Would you be able to create an in-app support chat session or open a support case? Please link to this forum topic and feel free to ask specifically for me (Angela). This way we’ll also be able to see historical connection counts for your Atlas cluster.
