request version: 2.76.x
system: Ubuntu

I'm using request via proxy with TLS, and after a long time I have thousands of socket ports in CLOSE_WAIT status, I google it , and find maybe the remote server force close my socket would lead to this, but what I want is to detect the event and close the socket gracefully or the ports will be exhausted and the process would never work.

Dose this related to #2438 ?

Thanks.
