Ouch, that is an old server you have there ...

I cannot say that upgrading will fix it, but there has been some changes 
along the way to how the memory-parsing code works. It also means that 
it will be difficult to provide any kind of patches to test.

Looks sane, and running it through my Linux/Intel test system here gives 
the correct result with 4.3.4.

The only possible bug I can see is that something weird happens when 
your compiler does the arithmetic because there are long int's and short 
int's involved. One thing you could try was to change the 
hobbitd/hobbitd_client.c file; in the "unix_memory_report()" function, 
remove the "unsigned" keyword from the declaration of the "memphyspct", 
"memswappct" and "memactpct" variables, and in the 4 "sprintf" commands 
below, change the "%11lu" formatting string to "%lld" (replace 'u' with 
'd').

No idea if it helps, but it might. But I would strongly recommend 
upgrading your Xymon server to 4.3.4.
