MongoDB Atlas - Non-expired  database connections

mertsarac · 2025-02-13T13:09:04.315Z

Hello,

Today, I noticed that some of my services were not working along with the warning ‘connections % of configured limit has gone above 80’. I believe there is a service that opens a high number of connections to the database and does not close them. By downloading the cluster logs from Atlas, I found the source that opens a high number of connections and terminated this traffic via network access. At this point, I also upgraded from M30 to M40.

After the upgrade process was completed, everything started working smoothly. I re-allowed the IP address of the source that opens a high number of connections and once again reached 2000 connections instantly. Currently, I have removed the permission for this IP address via network access. However, despite more than 30 minutes passing, I still see 2000 connections in each cluster. No new connections are being made since I removed the permission via network access, but the existing connections remain open. How can I terminate these connections? Or when will these open connections expire?

I am sorry that you are facing this challenge. Could you please share your cluster details and we can take a look?
