Thanks for the reply.
I didn’t know that it was attempting to build multiple projects at once…I was under the (incorrect) assumption that the build process was linear.
In VS, under the Tools->Options->Projects and Solutions->Build and Run, I found a setting to control the number of parallel project builds. This was set at 12 by default. I set it to 5, and it *seems* to have fixed the issue.
FYI, we are currently evaluating VGDB for use with our project. So far so good…
