Hi gentlemen,
I have a performance issue Win2003 32bits, SQLsvr2005, 8GB RAM, SAP ECC 5.0 Basis 6.40
It appears SAP workprocess are using all the resources of memory. CPU is 5% but memory is an issue.
The tasklist shows 11 GB as use of memory, of them the disp+work.exe processes are using 7.7 GB
The strange is that SM50 show just -active- 1 Dialog WP, the rest of WP are -waiting-.
So, why the WP not running (waiting) are using a lot of memory and why are not releasing it???
Please help!
