Error while printing (PDF) large BI reports

Question

Hello,
We use ADS to print our BI reports from the portal. For small reports (10-20 pages) this works fine, but for very large ones (>100 pages) we get the error "Error while generating PDF" on the screen (after a considerable amount of time). In the defaulttrace, I can see this error:
Exception thrown: com.sap.ip.bi.base.exception.BIBaseRuntimeException: EXPORT XFA exception when calling the PDF object after 261430 msec
com.sap.ip.bi.base.exception.BIBaseRuntimeException: EXPORT XFA exception when calling the PDF object after 261430 msec

     at com.sap.ip.bi.export.controller.ExportResult.createExport(ExportResult.java:73)
I've checked the timeout settings for IRJ services (500 seconds) and the timeout settings for web service clients (900 seconds). This should not be the problem.
Does anybody have a suggestion as to how to solve this?
Kind regards, Wilbert
