I have a LAMP server and recently I have been getting requests that timeout. When inspecting the request in Chrome the timing tab states that it "Stalled" for 30 seconds. I have no log of the request in the Apache logs and so I'm stuck as to what could be causing it.
I had a look into what "Stalled" could mean and most posts mention having more than 6 simultaneous requests and waiting for an open connection. However the request that is stalling is the html document, so no other requests can be loaded until the document has finished.
