First I'd like to say thank you to Henrik and the other Xymon developers for all their hard work on this program.
We are running Xymon 4.3.0 beta 2 client running on HP-UX 11iv3 Itanium with non default (4k) memory page sizes. We discovered a problem with Xymon memory reporting on HP-UX 11iv3 when we increased memory page sizes from 4k to 16k or 64k.
The Xymon program hpux-meminfo located in ~client/bin has incorrect reporting with HP-UX 11iv3 Itanium, for example:
On an HP-UX 11iv3 server with 32GB of memory (with about 15GB free) and 16k memory page size the hpux-meminfo program reports:
Total:8190 #Looks like the included hpux-meminfo grabs the wrong output lines. Free:3328
Here is the complete output of swapinfo -tm:

Here is a script we created to replace the hpux-meminfo binary that comes with Xymon 4.3.0 beta 2.
