Hello, i have a CAS Architecture with primary (Yes i know....)

I receive a lot of and no more WKS are reporting to SCCM.
2022-09-06 12:14:31.012 UTC Warning w3wp.13 WebService.ValidateEventBatch Event in batch failed to validate. Exception: "ReportingEvent is invalid. Size 498624 of field ExtendedData.MiscData exceeded the

Thanks for your help.
 
Hello, yes No scan WSUS is low. But i still have the error after apply some modification in webconfig.

Please login to FOS Site server and open IIS.

  • Find web.config file under %programfiles%\Update Services\WebServices\ClientWebService on the WSUS server
  • Copy the web.config file to the desktop
  • Locate the following line in web.config: <add key="maxCachedUpdates" value="22000"/> <add key="maxInstalledPrerequisites" value="400"/>.... Change the value from 22000 to 44000, from 400 to 800
  • maxRequestLength changed from 4096 to 8192
  • Save the web.config file and move it back to %programfiles%\Update Services\WebServices\ClientWebService
Go to Application Pool > Select WSUS Pool > Advanced Settings > modify below values
  • Queue Length from 2000 to 25000
  • Service Unavailable response type from HttpLevel to TcpLevel
  • Failure Interval from 5 to 30
  • Maximum Failure from 5 to 60
  • Restart IIS service
Please apply following changes and observe the behavior, if issue still persists, please let me know.
