Hi Everyone,

I recently made a 
post<https://boinc.berkeley.edu/dev/forum_thread.php?id=11538> on the Boinc 
message boards about some issues the 
Sourcefinder<http://54.196.169.236/duchamp/> project has been having with 
VirtualBox. I was told that I should post the issues to the boinc_dev mailing 
list.

I've compiled a list of the most reported / problematic issues, and I hope 
someone on here can either provide me with solutions to said issues, or point 
me to where I can find solutions :).

Here's a list of the issues:
Vboxwrapper lost communicaion with VirtualBox, rescheduling task for a later 
time.
The task had technically completed, but according to the logs and the user, 
virtualbox fully re-started the work unit.
Reported: http://54.196.169.236/duchamp/forum_thread.php?id=168

Error 194 (0xC2).
Work units end computation with that error code whenever the computer is 
restarted without first closing Boinc and waiting for VirtualBox to suspend the 
application.
This may be un-avoidable, I’m not 100% sure.
Reported: http://54.196.169.236/duchamp/forum_thread.php?id=36
Stderr: http://54.196.169.236/duchamp/result.php?resultid=13106

Some work units don’t seem to actually do anything.
Looking at the stderr output from some work units, the actual client 
application simply doesn’t start.
This example result had almost no CPU time, despite running for several hours:

Another user reported work units that appear to continue forever without 
progressing:
http://54.196.169.236/duchamp/forum_thread.php?id=28

Suspended work units wont re-start.
One user reported that if they paused work units, they would never resume.
