Hi everyone, I’m encountering a VERY strange “connections to your cluster(s) have exceeded 500” in my M0 cluster, and can’t seem to make it go away no matter what I try. For context, our atlas cluster is accessed exclusively through a Mongodb Realm app, through the app.currentUser. We use realm-web v1.2.1 nodejs driver.
A few puzzling things about my situation:
- there should be no users currently using it, it’s a development instance and both developers were offline/asleep. Even so, it’s maintained ~500 connections for the last 24+ hours
- the only op type in the Opcounters graph is “commands”. There are no queries/deletions/updates/etc for the last 24+ hours, yet there is consistently 15 “commands”/second to the cluster somehow.
I have tried:
- killing all hosted/adhoc instances of the webapp which is using Realm. This did nothing.
- removing all ip addresses from the Ip Access list in Network Access for 30 minutes, so theoretically nothing should be able to access the cluster. Even so, connections remained elevated at 500.
- Finally, I disconnected my Realm app from the atlas cluster as a data source entirely. Finally after this, the # of connections is going down by about 3 per hour.
Does anyone have any guidance on what could possibly be going on here, and what I can do about it? The opaqueness of the situation is a bit frustrating. We were pretty sure we were going to upgrade to M3+ eventually once the app had a real launch, but need to be confident we can work through critical fires like this.
Thank you.
