Unbalanced background load distribution in SAP batch servers

Hello,

We are having 5 application servers (Say for Example - ERP1, ERP2, ERP3, ERP4 and ERP5) with 30 BG work process each. (Back. WP Class A - 5 on each application server)

We have maintained 4 job server groups (PUBLIC, SAP_DEFAULT_BTC, DEFAULT and SPACE). We have included all the 5 application servers in all the batch server groups

I see all the Released jobs in the system are defined in either of the Target Servers we defined in the Job server Group

We still see the load distribution is not equal between servers.

Every day we are seeing that the load on ERP4 is almost three times when compared riple to other application servers.

The rest of the application servers are alsmot sharing the same load with or 10 jobs in count.

Below is for one day i have pasted

Legend:

Long Running Jobs = Job duration more than 15 minutes

Shorter Jobs = Job duration less than 15 minutes

Any suggestion what to check ond find out why a singlw application server is overloaded?

Thanks,

Subbu
