Export to Excel not working

When we click on Export to Excel buttons we're seeing a large number of these: Opening JDBC connection failed with SQLState: null Message: Cannot get a connection, pool error Timeout waiting for idle object, giving up...(3/3) followed eventually by an out-of-memory crash. Can anyone explain what might be going on please?

The message "Opening JDBC connection failed with SQLState" can be reported in two situations:

  • The Mendix Business Server cannot connect to the database at all.
  • All connections between the Mendix Business Server and the database are occupied. You adjust the maximum number of connections in application.conf by changing/adding this line: ConnectionPoolingMaxActive = 500
