Carlos,
If you anything more than 10users on your system, you are way TOO low in overall memory. You need min 40 to 48Gig of memory.
Approx Memory allocation required:
- ~ 4 to 6 Gigs for the OS alone
- ~ 12 to 20 Gig for all the APS
- 8Gigs for the DSL Bridge alone
- ~ 8 to 10 Gigs for other BI4 Servers
- ~ 4 to 6Gigs for WebI Process
This a very high-level without knowing your environment.
Please have a look at the sizing guide for more details
Sizing and Deploying SAP BI 4 and SAP Lumira
Any reason you still need to run BI 4.0 w/ SP4, why have you NOT updated to BI 4.1 w/SP7. The APS wizard would help you split the APS server much better.

Ajay
