>=net-p2p/qbittorrent-4.5.4 makes a system to reboot in a kind of Poisson process: if qbittorrent is running, system will always rebout in a random time from several minutes to several hours.

Userspace programs cannot normally cause a system reboot with no trace in the logs. This is almost certainly a kernel bug or a hardware issue. You will need to somehow collect more information for anything useful to be done with this bug report. The kernel log (dmesg) would be a good starting point. A colleague also suggested setting up a network console to try and capture it.
You might also consider switching to a newer or older (LTS) kernel to see if the problem still occurs.
We can not help you efficiently via bug tracker. The bug tracker aims rather on specific problems in .ebuilds and less on individual systems. I have had very good experience on the gentoo IRC [1] with questions like this. Of course there are also forums and mailing lists [2,3]. I hope you understand, that I will close the bug here therefore and wish you good luck on one of the mentioned channels [4]. Please reopen the ticket in order to provide an indication for an specific error in an ebuild or any gentoo related product. [1] https://www.gentoo.org/get-involved/irc-channels/ [2] https://forums.gentoo.org/ [3] https://www.gentoo.org/get-involved/mailing-lists/all-lists.html [4] https://www.gentoo.org/support/
I understand that this is very strange (I work with Linux workstations more than 20 years and never seen anything like it). Syslog simply does not keep up with the crash. I will try to set up kdump system. For a time being, I have installed 4.2 version of qbittorrent, and all is OK.
Stupid question, but I have to ask: Are you running qbittorrent as root? If so, that makes rebooting the system trivial and there could be several different ways for that to happen.
(In reply to Mike Gilbert from comment #5) God forbid, no.
