Paginated Report throws Sys.WebForms.PageRequestManagerServerErrorException (503 Error)
Hello, here an update:
It looks like the trellix endpoint security service was the reason. We created a policy to exclude the directory "C:\Program Files\Microsoft Power BI Report Server\PBIRS\ReportServer".
Now it works
Hi MORATHO
The Sys.WebForms.PageRequestManagerServerErrorException (503) error in Power BI Report Server (PBIRS) occurs after applying patches KB5050182 and KB5050008, causing the ReportingServicesService.exe process to crash due to a .NET runtime issue (exit code 80131506). Reverting the patches restores functionality, indicating a compatibility issue introduced by the updates. Since the May 2024 version (1.20.8944.34536) has been running smoothly, the problem likely affects newer builds. To address this, you can rollback the updates, check Microsoft forums for known issues, and verify if the .NET Framework version has been impacted. Restarting PBIRS and reviewing logs (C:\Program Files\Microsoft Power BI Report Server\PBIRS\LogFiles) may provide more insights. If necessary, contact Microsoft Support for guidance or wait for a future patch to resolve the issue. Testing updates in a non-production environment before applying them in production can help avoid similar disruptions in the future.
Hello,
oh, SSRS 2024 ran smoothly until the patches came out. Now also the Mai 2024 version causes the same issue.
We are forced to update the server so not applying the Server Patches ar ento an option
The logs (C:\Program Files\Microsoft Power BI Report Server\PBIRS\LogFiles) have no entry for the requests which are causing the error. This make sense, since the whole service is crushing (out of the windows Event logs)
