The maximum number of seconds that a given connection can be used before it is destroyed. Connections whose lifetime exceeds the specified value are destroyed as they become available. (This might cause the number of connections in the pool to temporarily fall below the
PROGRESS.Session.minConnections value.)
An available connection is one that is not currently reserved to run a request. Bound connections associated with remote persistent procedures are not available for reuse until the persistent procedure is deleted. As a result, bound connections remain available as long as necessary, even if they exceed the specified value.
