As a short term solution for the problem reported by Shawn Webb re: r359950, bump the maximum number of memmaps per VM. This structure is 40 bytes, and the additional four (fixed array embedded in the struct vm) members increase the size of struct vm by 3%. (The vast majority of struct vm is the embedded struct vcpu array, which accounts for 84% of the size -- over 4 kB.)

FreeBSD is an operating system used to power modern servers, desktops, and embedded platforms. A large community has continually developed it for more than thirty years. Its advanced networking, security, and storage features have made FreeBSD the platform of choice for many of the busiest web sites and most pervasive embedded networking and storage devices.
