[vbox-dev] Excessive load averages with nothing running.

[Alessandro Suardi]

Linux bumps up load average by 1 for each process in D state - so the point here
 is not that something is being used (it isn't), but why is
iprt-VBoxTscThr in D state?

Devs might find helpful a

 $ ps auxww|grep iprt-VBoxTscThr

 since that would should the kernel WCHAN where the thread is stuck.

Cheers,
