[Xymon] calculation of memory and swap

Upgrading to the 4.3.10 client fixed out oddball negative memory reports, which we had on servers with more than 128G RAM

I'm guessing 8G (rather than 10G) would be the threshold, as it's a power of two.  Are you able to reduce the zone's RAM allocation to a little greater, and then a little less than 8G to see if this is the case?  Or do you have examples of correctly displayed values greater than 8G and less that 10G?  By 8G, I mean exactly 2^33=8589934592 (or perhaps one less).
