This is a very odd issue we’ve been experiencing for awhile, and I always chalked it up to it just being a dev server (localhost) and can’t handle very many requests. It started happening after adding Server Sent Events to our app (roughly).
But it’s gotten to the point where I can’t even load two tabs to do user permission testing in my app. When opening the second tab to localhost:5000, the content and data either doesn’t load, or half-load and spinners just keep spinning. It acts as though it simply can’t handle any more requests.
Like I said it seemed to start after we added server sent events. It’s especially strange because lets say I open two tabs, the first one loads fully, the second is stuck spinning. Then I close the first tab, the second one finishes loading. Is there some setting in ServiceStack Web host or in server sent events that we can change to allow more requests or remove limits?
