Xymon-4.3.0-beta1: incorrect value for "count" rrd

[Dominique Frise <dominique.frise (at) unil.ch>]

Hi,

We track "surgemail" processes using following rule in hobbit-clients.cfg:

HOST=xyz
    PROC ./surgemail min=0 TRACK=surgemail

The ps listing in msg.xyz.txt reports 315 "./surgemail" processes, while 
the rrd graph only shows ~30 processes.

Here the last corresponding dataset of processes.surgemail.rrd file 
(after flushing the cache by stopping Xymon):

<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE rrd SYSTEM "http://oss.oetiker.ch/rrdtool/rrdtool.dtd";>

We tried to let Xymon recreate a fresh rrd without success.
The same configuration was working with Hobbit-4.2.0/RRDtool 1.2.19 
(same version)

The rrd-code has pretty changed since 4.2.0 and I don't really see what 
code is involved to try debugging this.
Any help appreciated!
