This INTEGER reports total virtual memory on the gateway using a legacy 32-bit counter, explicitly noted in its description as superseded by the 64-bit memTotalVirtual64 object for accuracy on modern hardware. Because 32-bit counters can wrap or misreport on machines with large amounts of memory, this field is only reliable on older, smaller-memory appliances, and the description itself warns against trusting it on 64-bit machines. An admin monitoring a modern high-memory appliance should read memTotalVirtual64 instead and treat a suspiciously low or wrapped-looking value here as an artifact of 32-bit overflow rather than a real capacity number.
