I'm trying to fix a problem where we are getting high rendering times from SSRS 2017 at different points in the day.
Around the same time that we are experiencing rendering problems, not always - but often, I've found an event like this in the event log, and I was wondering if I could get some help interpreting what it is and solving it:
(I'm going to anonymise some server names, report names, etc, because - business - they'll be in <BRACKETS>).
The description for Event ID 1309 from source ASP.NET 4.0.30319.0 cannot be found. Either the component that raises this event is not installed on your local computer or the installation is corrupted. You can install or repair the component on the local computer.
If the event originated on another computer, the display information had to be saved with the event.
The following information was included with the event:
3005
An unhandled exception has occurred.
