Created attachment 456376 [details] emerge --info With both app-emulation/virtualbox-5.1.10-r1 and app-emulation/virtualbox-bin-5.1.10.112026, running virtual machines get aborted when the screen locker/screen saver of the host system is active for some time. I was not able to find out the amount of time it takes, as it does not happen simply when the screen saver is activated. It appears that the machines segfault whenever the screen is locked automatically by the screen saver (after 300 sec in my case). If I manually lock the screen and then unlock it within some minutes, the problem does not occur. If the screen is locked automatically and I unlock it again within some minutes, the problem does not occur. So this happens only after the screen has been locked for some minutes (sorry for not being able to be more precise on the timing). The only notice in ~/.VirtualBox/VBoxSVC.log is 11:49:58.398549 Watcher Reaper: Pid 11703 (2db7) was signalled: 11 (0xb) The system is amd64 with kde/plasma. The problem does not occur with virtualbox-4.3.38.
I suppose this still happens with latest virtualbox-5.1.x versions?
