App pool is crashing and resulting in all sessions timeoutWe are seeing strange thing -- when one person times out, everyone receives the time out. What that means is the application pool or WSL5 agent is crashing. However, we are having trouble figuring out why -- other than that it seems the more traffic we have on the site, the more frequent this happens. We are on .Net Framework 4.7.2 and using IIS 10.
