"Long request time" errors in OrionWeb.log leading to web UI crashing

Since upgrading to 2020.2, almost any time a user loads a node, interface or application page with the new charts, I get these errors in the web site log and the page never finishes loading. If the user leaves the page loading, the web UI will eventually crash requiring either a restart of services on the primary poller or a restart of the poller.

Has anyone seen this?

can you try and remove all temporary ASP.NET files and also the files in - c:\Users\username\AppData\Local\Temp

Along with your suggestion, these are the things that were recommended by support that I tried yesterday. I then reran the Configuration Wizard. This seems to have corrected the crashing of the web server (for now), but the referenced charts still never load. I have a feeling that over time, they may start crashing the web service again if I can't get this figured out.

Clear queues to address the long request times and long running queries:
Clear or purge RabbitMQ queues:
Clear Information service:
Repair the Information service:
Make sure that you put files and folders exclusions for Solarwinds from your Antivirus, as it looks like some files are being locked up by your antivirus:
Adjust the ephemeral ports or follow the article below to tweak the server for best performance, this is because of the socket connection time outs, and also the error below:
"FATAL SolarWinds.Orion.Core.Common.RemoteFeatureManager - (null) Unable to load Feature Manager data from SWIS"
Please follow the article below:
