High Memory usage by disp+work

[Former Member]

HI all,

We had an issue today where a couple (about 9) disp+work prossors where taking over 1.3GB or RAM each with the highest topping out at just over 2.5GB.

System:

HP RX8620 (itanium)

SAN Attached (HP EVA6000)

Win2003 SP2 IA64

32 GB RAM

8 x IA64 CPU's

SQL 2005 SP2 (IA64)

My concern here is that with all this RAM being taken up by disp+work the system started to page at a high rate which then caused my SQL instance to slow to a dragging pace which caused the application to slow as well :-s

I'm fairly new to SAP... so go easy on my 😛

Thanks in advnace,

Paul

Hi,

2.5 GB does not seem so high on a 32 GB Itanium Host.

We ahave had the same issue on a 16 GB itanium server because the memory quotas were not correctly defined.

We have now limited the heap memory quota to 4 GB per process which means we get a memory short dump after 2GB in extended memory + 4GB of heap memory.

We have also limited the number of processes in private mode.

The system runs now OK and is protected from heavy swapping.

Regards,

Olivier
