When an asynchronous task is executed, the amount of time it takes to process the request is dependent on various factors, such as current server load, server processor capabilities, network bandwidth, etc.
If an asynchronous task spends more time in the 'waiting for activation' state than is allowed by the value of this property, a TimeoutException is thrown.
