            Bug ID: 230402
           Summary: With buildworld, the system can not use swap
           Product: Base System
           Version: 11.2-STABLE
          Hardware: amd64
                OS: Any
            Status: New
          Severity: Affects Only Me
          Priority: ---

Preprocessed source

I run FreeBSD 11.2-STABLE r337132 inside the virtual machine in the Virtualbox.
Machine configuration: CPU 3 core, 1GB RAM, 1x SATA HDD 14GB with FreeBSD
11.2-STABLE r337132.

According to the system logs, with buildworld there is not enough RAM, but at
the same time, swap remains unused.
