To deal with this issue, we have implemented retries on the service mesh level (Istio). In Django settings, the configured value of CONN_MAX_AGE parameter is the default 0, which means Django opens a new database connection for every query - this means that the observed failures cannot be related to RDS proxy's idle client connection timeout setting, which we have set to 30 minutes. This suggests that RDS proxy closed the client connection. Over the last month, we have started noticing occasional 500 "Internal Server Error" responses from our web app with the following error coming from Django:ĭjango.db.utils.OperationalError: connection to server at "" (), port 5432 failed: server closed the connection unexpectedly OKĪpplying members.0003_rename_members_member.We have deployed a Django application in EKS and used RDS PostgreSQL with RDS proxy as a database backend.
