strange behavior of xymon client in openSUSE

From an opensuse linux, i'm trying to connect to my xymon servers...
take a look at this..

in /etc/default/xymon-client

This works XYMONSERVERS="10.129.13.2"
This works XYMONSERVERS="10.10.100.100"
This doesn't XYMONSERVERS="10.10.100.100 10.129.13.2"

This works
XYMONSERVERS="10.10.100.100"
XYMONSERVERS="10.129.13.2"


linux:~ # cat /etc/os-release

VERSION_ID="42.3"
PRETTY_NAME="openSUSE Leap 42.3"
