Analysis 1:

1. Go to ST03N

Expert mode -> Workload -> Total -> wednesday

2. Under Analysis Views -> Memory usage statistics

Now on the you will be able to find out the REPORT (or) program that uses the max amount of extended mem in the tab transaction. You will be able to find out the user who uses the max amount of extended mem in the tab user

Analysis 2:

1. Go to ST02

Double click on Extended memory

2. Select the icon mode list

Here you can get the details about the user who has used the heap memory

Hello,

There are 2 possibilities:

1. Increase the extended memory value in profile

2. For sure there should be some user (or) program trying to utilize more ext memory. You have to analyze that report.

Hi

Did you increase the number of work process of your instance?

Also, check in SM04 - Go To - Memory, and check if you have some user with large amount of memory allocated.

Sometimes some RFC sessions hangs and after users log off the session is still "live" and allocating memory.

Another cause could be allocation memory from some work process (at os level) . If this is the reason you can restart the wp manually and you can prevent it configuring the following parameters:

rdisp/wp_auto_restart

Hope this help you !
