SAP Message RT158 - &1 &3 > &2 &3 Background work process load exceeds threshold

Diagnosis
This message describes an alert in the CCMS monitoring architecture.
Here, the monitoring architecture reports that the utilization ofbackground work processes has exceeded the threshold.

Procedure
Excessively high utilization may mean that background work processes arebeing blocked by long-running background jobs, or that there are toomany jobs for the background work processes to handle efficiently.
The consequence of this problem may be delays in starting backgroundjobs that are ready to run. Such delays can be important if, forexample, long-running jobs are substantially delayed and cannot becompleted in the timeframe that you have planned. The alert monitoralso reports on the length of the background processing queue. Ifbackground job-starts are being delayed by the high utilization, thenthe queue lengths will rise.
To solve this problem, evaluate your background processing workload. Iflong-running jobs are causing the high utilization, then shift thesejobs to a time period in which your system is optimized for backgroundprocessing. (See the CCMS operation mode functionality. Operation modeslet you reconfigure your system on the fly for background processing ordialog operation.)
If there are too many jobs for the background processing system tohandle or you have already concentrated long-running jobs in anoperation mode for background processing, then you should add morebackground work processes. In extreme cases, it may be necessary to addbackground processing server (SAP application servers that offer thebackground processing service).
You should also check for background processing jobs that are run inparallel (see the background processing documentation for moreinformation). Ensure that parallel jobs are not competing for resourceson the same application servers.
