Suppose I'm using the DB element and the app server's been configured to have a maximum of, say, 20 connections to the DB. What happens to that 21st concurrent request to use the DB?

Will the app server queue up this request until one of the DB connections is freed?

--If so, then how long will the application wait for a connection before an error is thrown?

--If not, then what event/error does the application experience, and is it immediate?

Thx, Janine
