Disp+Work memory comsuption

Former Member

Hi All,

Sometimes we note that a work process uses about 2.7GB of memory and when we look at the Tcode SM50 to see what is running there is nothing running, does anyone know why this happens?

Obs.: When we cancell the process using SM50 the process starts again at the Operational System using less memory,

Best Regards,

If it is a batch process, then the behavior is controlled by abap/heaplimit (default 40mb), this means when a process consumed more than 40mb it will automatically be restarted and the heap memory will be freed. So check for abap/heaplimit.

Dialog work processes use shared memory (extended memory set by em/initial_size_MB). As this is shared memory it won't be freed unless you restart the whole application server. You may see a different number after restarting a process but this most probably doesn't mean much.

Only if the extended memory is exhausted dialog processes start using heap memory. This is called going PRIV. This should be avoided, as the process is blocked for all but the current SAP user. You can see this in SM50.

i think When you have enough em/initial_size_MB, priv memory and heaplimit is not necessary.

Hi All

The parameter abap/heaplimit was seted with a big value, we have changed the parameter and now the system is working fine, thanks all for the help,

Hi Andre,

The phenomenon you described about memory usage and SM50 actually depends on the application which is demanding memory here. Is this for a custom Z program or a standard SAP program ?

Shouldn't this discussion be in a "basis" discussion space, or in one of the generic Netweaver spaces? Please let me know where you would like it moved and I'll be happy to move it.

Good day,

1 - If you are using windows this could be a bug of windows controlling the workprocess.

2 - Its a distributed installation? remember a work process is in a Aplication server and you should see the task manager of that server
