It is the "[free]" section that is interesting for the memory report.
Here are two separate [free] sections (from history), that resulted in

I have to plead "not guilty" on behalf of Xymon, then. The data reported by "free" in the "+/- buffers/cache" line is obviously bogus - but it is
what Xymon uses for the "Actual" memory calculations. If Xymon gets bogus data, then you will also have bogus results.
