On my computer qBittorrent's desktop version works in a very high memory:

61557 yuri         21  21    0    83G  6907M select   7 978:47   4.54% qbittorrent

It is qBittorrent-4.3.3, libtorrent-rasterbar-2.0.2.

Does qBittorrent-4.3.3 leak memory?

[yurivict]

Right after launch the desktop app goes unreasonably high in memory:

17851 yuri         24  23    0    11G    94M select   5   0:03  22.27% qbittorrent

libtorrent-rasterbar-2.0.2

Is it possible to recompile and test with 1.2.x series? While qbt compiles with 2.0.x series we don't officially support it. Also those series haven't received other adoption yet so they may be quite untested and contain such bugs.

qBittorrent is still not ready for general use with libtorrent 2.x, there are PRs targeting master in progress for this, but problems with 4.3.3 are not an issue IMO.

I try deluge 2.0.3 ,have same problem, libtorrent-rasterbar 2 is not ok?

[FranciscoPombal]

Are you guys looking at actually used memory (i.e., is this memory really unable to be used by other applications)? See https://www.linuxatemyram.com/.

qbittorrent begin downloads ,I disconnect my ssh connection.
/var/log/messages,ttys be killed,and ,swap use lot.I link keyboard.The message display about the usb keyboard.But I can't control my keyboard.

With libtorrent-rasterbar-2.0.5 the memory in qBittorrent goes up into hundreds of gigabytes on FreeBSD:

  PID USERNAME    THR PRI NICE   SIZE    RES STATE    C   TIME    WCPU COMMAND
29462 yuri         26  22    0   109G   167M select   7   0:06  11.46% qbittorrent
