Yes. I'm assuning all your .rrd files are stored on the master.
Yeah ... I'm just making sure that we're definitely on the same page.
No ... I don't think that it is actually. The <lastupdate> time looks
like the initial creation date of the .rrds by the master machine.
You mean that in _your_ file it looks like the file isn't being updated?
Can you verify that this is not the case for files which are being updated?
Correct ... I'm talking about my own slave .rrd files. RRD files for
the master are updating fine though.
test.rrd [master]
<lastupdate> 1213980387 </lastupdate> <!-- 2008-06-21 02:46:27 EST -->
That's within 5 minutes of the current time here ... so obviously
updating properly.
test~david-slavebox.rrd <lastupdate> time is several hours ago.
Where does that put us then?
You have to find out why the master says to the slave that it has the
data but then the data doesn't manage to get written to the file. Are
the permissions on your .rrd files all the same?
Yes ... They're all owned by the smokeping user/group.
Here are the Apache processes on my master server:

Here are the processes owned by user 'smokeping'
tornado:~# >>> ps -o pid,fuser=User_Name,pid,pcpu,stat,comm --user smokeping
<snip>
Note that these processes haven't been running for very long, so they
haven't done very much yet. (I'll leave you to figure out why I had
to use that format specifier in the ps command line:)
Well mine has probably been running for even less time, because I just
put it through a restart. ;)

Here are the .rrd files for one part of the local network:
<snip>
As you can see, the .rrd files are all writeable only by the smokeping
user (and root, of course). The Apache user is 'www-data'. The Apache
Webserver (apart from the parent process, which does not serve requests)
can only read them.
Yep ... mine is setup the same.
