Diagnosis
The background job you have selected starts program RCOCB002 orRCOCB004 to send process messages. Another job for the same program wasalready running at the time for which you have scheduled the new job.
Since overlapping send jobs may cause errors, the new job wasterminated.
Lock parameters: plant &V1&, lock group &V2&

Procedure
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.
