Yeah ... I'm just making sure that we're definitely on the same page.

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.

Yes ... They're all owned by the smokeping user/group.

Well mine has probably been running for even less time, because I just 
put it through a restart. ;)
