I’m experiencing the same with Percona Operator for MongoDB 1.21.0 on AWS EKS 1.34.
After starting the Operator it keeps creating connections until it reaches OOM and dies. In my case this is around 8000 connections. It creates about one connection per second.
Please let me know what info I can provide to help find a solution.
