Mendix app deployed in the cloud randomly got very slow and then I was unable to load a page from the navigation. A progress bar started when I clicked on the page and the app gets stuck there. Client was not responding in any way. I checked the logs and this error was found. No further details available in logs and no other errors. What could be the reason for this error?
