I normally keep a qBittorrent session open on my desktop, but for the
past week or so I find it's been freezing, i.e. unresponsive to button
events. I have to kill and restart it. This doesn't seem to happen when
downloading a torrent (at least not so far) but at random quiet times.
An strace on the process shows:
$ strace -p 29850
strace: Process 29850 attached
futex(0x5632009da984, FUTEX_WAIT_PRIVATE, 1, NULL^Cstrace: Process
29850 detached
whereas normally it would get a continuous series of polls and
read/write calls.
This is qbittorrent-3.3.1-2.fc23.x86_64, installed nearly a month ago
and working up until 6 days ago. The only change in the interim has
been daily system updates including kf5 and Plasma, so I suspect that's
where the problem might be.
I reported this to the qBittorrent bug page but have had no answers in
nearly a week,
see https://github.com/qbittorrent/qBittorrent/issues/45

Any thoughts on how to debug this would be welcome.
