Olivier,
This is very generic error. It could be related to JAVA crash, APS not sized properly, WebI Process server crashing and even your over memory not sized properly.
Need more details:
- What is OS ? ver?
- How much system memory?
- Typically how many users on the system?
- How did you split the APS?
- Any custom memory setting for the APS?
- What type data source being used? BW/BICS or UNV/UNX
Regards,
Ajay
