Just build from source and it appears to work fine.

I've found this happens when one or more of the virtual disks have less than ~5GB free space. That's the only time I've ever seen this error.

Hi trltom, what do you mean by "Just build from source"? I have three virtual machines and only one is getting this error.

I downloaded the source code, compiled in Visual Studio, ran that version instead of the distributed download, and it worked on the same server which otherwise failed.
