"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?

Thanks!

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: https://support.solarwinds.com/SuccessCenter/s/article/RabbitMQ-troubleshooting-and-purging-SwisPubSub-Queue?language=en_US
Clear Information service: https://support.solarwinds.com/SuccessCenter/s/article/Clear-Information-Service-Subscriptions?language=en_US
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:
https://support.solarwinds.com/SuccessCenter/s/article/Files-and-directories-to-exclude-from-antivirus-scanning-for-Orion-Platform-products
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:
