The output from 'ps' would be a better indication of which user is running
the processes, but accepting for now that it is in fact the smokeping user
which is running them, then if you use the '--debug-daemon' switch when
you you start smokeping on the _master_, do you see anything like this in
the log file (/var/log/messages or wherever the hell it is:)

tornado:~# >>> grep Server /var/log/messages | tail -n 3
Jun 21 14:22:36 tornado smokeping[3458]: Calling RRDs::update(/var/lib/smokeping/Local/Server_SSH.rrd --template uptime:loss: [snip]
Jun 21 14:26:02 tornado smokeping[3451]: Calling RRDs::update(/var/lib/smokeping/Local/Server.rrd --template uptime:loss:medi [snip]
Jun 21 14:26:02 tornado smokeping[3451]: Calling RRDs::update(/var/lib/smokeping/Local/Server~mail4.rrd --template uptime:los [snip]

Note that the processes calling RRDs::update on my .rrd files are
running as user 'smokeping':

tornado:~# >>> ps axufww | grep smoke | grep 345[18]
116       3451  0.0  0.3  56880 21528 ?        S    Jun20   0:01  \_ /usr/sbin/smokeping [FPing_14]
116       3458  0.0  0.3  56880 21464 ?        S    Jun20   0:02  \_ /usr/sbin/smokeping [TCPPing]

and that (in my system at least) the files that they are writing are
writeable only by that user (and root of course):

tornado:~# >>> ls -l /var/lib/smokeping/Local | grep Server
-rw-r--r-- 1 smokeping smokeping 2986808 2008-06-21 14:36 Server~mail4.rrd
-rw-r--r-- 1 smokeping smokeping 2986808 2008-06-21 14:36 Server.rrd
