Max no. of Webi services possible on a single physical server

Hi All,

We have been facing the below errors -

1) The Web Intelligence server is busy. Please save any pending change and try again later. If the problem persists, contact your BusinessObjects administrator. (Error: ERR_WIS_30284)

2) The Web Intelligence server memory is full. Please log off and try to connect later. If the problem persists, contact your Business Objects administrator. (WIS 30280)

Our reports are very very complex and seem to be crossing the memory limits (Upper Memory Threshold =1500MB/Max Memory Threshold=1800MB)

Testing done from our end : We scheduled a very complex report, retreiving huge data, every 3 mins (scheduled a particular Webi Processing server)

Observations :

1) The first 4 instances of CST-2203 report ran successfully.

2) 5^th instance failed with following error message:

The Web Intelligence server is busy. Please save any pending change and try again later. If the problem persists, contact your BusinessObjects administrator. (Error: ERR_WIS_30284)

3) 6^th& 7^th instance also failed but the error message was:

The Web Intelligence server memory is full. Please log off and try to connect later. If the problem persists, contact your Business Objects administrator. (WIS 30280)

We went through quite a few SAP notes, specifically-

1482911 - talks about increasing Webi servers and reducing idle connection timeouts

1297195 - reducing connection limit, idle timeout, Adding Webi servers and hardware

Can you please help me understand the max no of Webi servers I can have on a single machine? (currently we have 4 webi services)

BO server specs :

-Microsoft Windows Server 2003 Enterprise x64 Edition Service pack 2

-No of CPU cores : 16

-RAM : 32 GB

-BOE XI 3.1 SP4 FP 4.2

-Physical servers
