Package: virtualbox
Version: 5.0.20-dfsg-2
Severity: minor
File: VBoxSVC

Here is something VBoxSVC doing all the time in background, although no
vbox instance is running and not even drivers are loaded. It's not much,
just a few syscalls per second according to strace, but it's still waste
of CPU cycles.

Hi, quoting upstream:

"Most likely a minor problem. Sometimes it's necessary to poll stuff, but don't 
ask me where we poll on VBoxSVC, there might be several places. Nothing we can 
fix at the moment, too busy with other stuff. This guy should report the bug 
upstream (at our bugtracker) and you should close it for Debian. He might even 
want to find out where we loop, perhaps with strace -i together with gdb."

this is the upstream bug tracker


https://www.virtualbox.org/wiki/Bugtracker

(feel free to connect this bug to the upstream ticket if you open one)

thanks

G.
