I should have taken a screen shot, I can't recall the exact phrasing.

Actually, I googled the errors when I saw them, to try to figure out what was going on, so I can check my chrome history and bring up the searches I did.

First error seen was "error reading from database" or some approximation, this was back on 0.10.0

"error reading from database, shutting down" was also occurring after my first attempt to fix the problem by rebuilding.

The last error (on 0.11) -

edit: Disk space is fine I think, had more than 20GB free when the error occurred last time.
