I think it's LC_NUMERIC that matters here. I think the underlying bug
here is that the server code uses sscanf() to parse uptime, and I guess
that's not properly locale-aware.

A possible workaround if you want to maintain your locale comes from
noting that xymonclient-linux.sh just runs "uptime" which thus
implicitly uses whichever "uptime" is first on your path. On my systems
that's /usr/bin/uptime, so I could provide /usr/local/bin/uptime with:

#!/bin/bash
LC_NUMERIC=C /usr/bin/uptime

to just run uptime with the expected locale. Or, I see multiple sscanf()
calls in xymond_client.c so maybe there are similar bugs lurking
elsewhere... So, you could edit the xymonclient-linux.sh script sent by
xymon-rclient.sh and put

LC_NUMERIC=C
(and perhaps other locale variables if necessary? Or just LC_ALL?)

at the top of the script.

Adam
