High Memory Consumption at OS Level

[former_member753633]

Hi SAP Experts,

this query is related to High Memory usage of the server hosting application server. We have an application server installed on RHEL. It has physical memory 32 GB and Swap 64 GB.

em/initial_size_MB - 20480 (20 GB)

ztta/roll_extension - 4000000000 ( 4 GB)

abap/heap_area_total - 6500000000 (6.5 GB)

In ST06 we see the free memory most of the time remains less than 5%. When I check the application server SM50, majority of the work process are free.

I would like to know how the memory consumption can be reduced. What other things can be checked before making the decision of increasing the RAM of the server.

Will reducing the total number of work process help ( personally I feel that if they are free, they should not increase the memory foot print, so this will not work )

Any inputs / guidance on this, is highly appreciated.

I don't not see any blog or note particular to such concern.

Thanks,

Diwakar

Hi Gaspar,

I understood the Notes shared by you. But I would like to know, how can we decrease the memory consumption, provided the situation I have explained.
