VM server went down again — back up now

The VM server went down again last night.  It’s back up now, but I’m not happy that this has happened so frequently.  We’re looking into what’s going on here.  Later this week, we’ll have a redundant GPU AS which will minimize the impact of this machine going down, but still we need to find out the root of what’s going on here.  It’s possible that VM server is hitting end of life and having some hardware issues.
