Stuck or slow pending requests

[Magnuti]

Describe the bug

When using the Vite dev server some requests seems to be stuck in a pending state, or they take over a minute to complete. The debug logs does not indicate that this is an issue other than that they take over a minute to complete.

What's particularly odd is that the affected file in this case, uiData.js, is quite small. So, it's puzzling why it's taking so long to load. All other requests only take a few milliseconds.

This is a relevant issue but it's conversation is locked #5310

I have already tried to increase the open file limit without any success.

$ ulimit -n    
10496
