Symptoms

You have a custom J2EE application running in Oracle Portal as portlets.
This application is used to maintain customer, contacts and their activities.
You are trying to export a list of activities by a sales representative for a whole year.

If the list has more than around about 300 entries, the export fails with the message "Internal Server Error".

Apache error log shows:
