How to fix this error?

Change the job definition as follows:
If until now the send job has been started by a specific event such as
the creation of new process messages and this event happens too often,
start the send job at predefined time intervals instead.
If the send jobs have already been started at predefined time
intervals, define a longer interval between the individual jobs.
