ERROR - ConnectionBus: Opening JDBC connection

0
Hello, When we increased the load on the application, we are seeing the below error logged multiple times. We tried increased the ConnectionPoolingMaxActive and ConnectionPoolingMaxIdle but it did not fix the issue. Is there any configuration or custom setting that can be updated within Mendix to fix it? "ConnectionBus: Opening JDBC connection to Some(database) failed with SQLState: 08S01 Error code: 0 Message: The TCP/IP connection to the host database, port XXXX has failed. Error: "Address already in use: connect. Verify the connection properties. Make sure that an instance of SQL Server is running on the host and accepting TCP/IP connections at the port. Make sure that TCP connections to the port are not blocked by a firewall.". Retrying...(1/4)" Note: We don't see the error if we add one more server to the cluster or decrease the load.
