Description

It's a follow up of #5097 I finally got to reproduce a long closure case with asio-debugging enabled.

qBittorrent info and operating system(s)

qBittorrent version: 4.3.6 (stable from official arch package)
Operating system(s) where the issue occurs: EndeavourOS (Arch Linux based)

If on Linux, `libtorrent-rasterbar` and `Qt` versions

Qt: 5.15.2
libtorrent-rasterbar: 1.2.x git @33a10d5a7

Detailed steps to reproduce the problem

run qbittorrent in the terminal
wait for UI to appear
ctrl-q to close qBittorrent
check the terminal to see that qBittorrent takes several minutes to close.

What is the expected behavior

Closing in less than 10sec. Not sure if that's a reasonable expectation but a too long time hinders closing and restarting QBT when needing to wait it to close for a too long time.

Extra info (if any)

Source based package for libtorrent:
https://aur.archlinux.org/packages/libtorrent-rasterbar-1_2-git/

With the addition of this build flag -DCMAKE_CXX_FLAGS=-DTORRENT_ASIO_DEBUGGING

About the logs. QBT spends by far most of the time in the last "Waiting to shut down EXPECTS NO MORE ASYNC OPS"

The Waiting to shut down number can range from 2 to 23 after a few tries.

The measured timed ranges from 2:30 to 3 min

Attachments

terminal logs

In ~/.local/share/data/qBittorrent/ the only new log line when ordering QBT to close is (I) 2021-07-08T19:19:36 - UPnP / NAT-PMP support [OFF]
