Are you connected to any other projects successfully?
You can try looking at the Event Log under the Tools menu or Crtl + Shift + E

Does it say anything helpful?

I don't think the ATLAS task like to be started and stopped.
I would pick a single project application to run and stick to only that for now.
You can also work through Yeti's checklist. It's a sticky in the forums.

Your picture shows an ATLAS task waiting to run at about 8 minutes in. It takes about 15 minutes before the computation phase of ATLAS as it is talking CVMFS and getting needed files and info.

I don't see any aborted ATLAS tasks listed under your computer. Two CMS apps show aborted

Did you set LHC to No New Tasks, abort non running tasks or allow the queue to clear before your VirtualBox upgrade? That is usually the best procedure.

Is the VM RAM size going to be adjusted eventually or will the current defaults be used because 3.01 can run 'Run 2' and 'Run 3'? Will the VM change the RAM assigned by 'Run 2' vs 'Run 3'?

The one posted doesn't show anything obvious. Have you tried working through the Yeti checklist in the forums?
We would need to be able to see the individual computer stats and look at some of the logs on the work units and get more details.

26202 is a problem wrapper per the link https://boinc.berkeley.edu/trac/wiki/VboxApps#Premadevboxwrapperexecutables as it uses the COM interface.
26203 is reporting in the logs as '26202' and really should be reporting its own version number.

The bad WUs in this forum thread took care of themselves. It looked to be more an error of CVMFS within the VM hanging and the processing never starting.

Yours all seemed to stop shortly after the 'Checking CVMFS' section.
I see 'Radical Guest time change' in successful tasks so I don't think that is the problem issue.

Post:
I have 13 valid tasks as of this morning. Everything has been running smoothly besides the one task yesterday that just hung and got a computation error.

I think the vboxwrapper should be updated but developers need to figure out where the wrapper is getting its naming as the version of the file name doesn't exactly match the version reported in the task logs. i.e. vboxwrapper_26203_windows_x86_64.exe (file version 7.17.26202.0) reports as 26202 and Atlas wrapper vboxwrapper_26198ab7_windows_x86_64.exe (file version 7.7.26197.0) reports as 26197. Is this something in the source code and compilation? My finding are only on Windows as I don't have a Linux setup to check.

If anyone has tasks that just hang without processing, I would recomend posting the stderr.txt log and the task name details so those can be, possibly, followed up on to see if anything is common. I don't see any of this as a VirtualBox problem besides getting the best wrapper to minimize Postponed / lost communication issues.

I looked at my successful tasks and it looks like it is hanging at the CVMFS check or something, mounting shared files and then copying files into RunAtlas.
Below is from a successful task where I think it may be failing or getting hung. Just a theory.
