All your allocated memory (~43 GB) is fitting in RAM (you should tell how much RAM you have and how it is used) so your swap area is currently completely free (no pages are stored there). However, a part of RAM+SWAP is reserved (~34 GB) to guarantee future potential use (Solaris doesn't overcommit memory unlike Linux and others). The reserved memory explains the discrepancy.

NAME
vzcalc - calculate resource usage of a container SYNOPSIS
vzcalc [-v] CTID DESCRIPTION
This utility displays the share of the host system resources a particular container is using. If the container is running, the current usage is displayed. High utilization values (>100%) mean the system is overloaded (or the container has an invalid configuration). Current Shows the amount of the resources consumed by the container at a given time. Promised Shows the resources soft limit values "promised" for a given container. Max Shows the resources hard limit values "promised" for a given container. If the -v option is specified, the following additional information is also displayed: Low Mem The part of memory residing at lower addresses and directly accessed by the kernel (only makes sense for 32-bit architectures). Total RAM Total memory. Mem+Swap Amount of memory available for applications (both RAM and swap space). Alloc Mem Standard memory allocations made for applications in a container. This is a more "virtual" system resource than RAM or RAM and swap. Num. Proc Number of processes. OPTIONS
-v Display additional information. EXIT STATUS
Normally, the exit status is 0. On error, the exit status is 1. LICENSE
