Investigate Out of Memory issues

[tst-ccamp]

Background: When I ran the run_tutorial.sh script with 4 GB of RAM on RHEL 7 it did not build the projects correctly even though it claimed to have succeeded. 8 GB of RAM worked fine.

There may be other scenarios as well that fail when the system runs out of memory. Devise a test that will cause an out of memory error and try to replicate the behavior of failing to generate all the required data. There will also need to be an investigation into which process causes the issue.

There have been a number of memory improvements since this time, so it is likely that the behavior won't happen exactly the same. However, it's still worth investigating how Fusion can fail silently when memory is constrained.
