This test fails about 20-25% of the time - ran about 10 times through looping the test, and it typically fails on the 4th or 5th test.

    done
    unset MAX_HEAP_SIZE HEAP_NEWSIZE PRINT_DEBUG

    echo "  ${0} needs a test to run.."

I find no ERROR/WARN log entries from the failed test - attached node log anyway.
