[hobbit] Loss of Apache graphs

[Rob Munsch]

Hmm.

Well, there are two webservers; one is showing apache graphs, the other 
isn't.
Went ahead and added 'em to a (pretty aggressive) rotation schedule; 
rrd-data.log is 600k, rrd-status was about 3.5M.  Just in case, 
rrd-status is now limited to 1M.

Stopped and restarted the server, but no apparent effect.  The server 
that had its Apache graphs still does, and that one that doesn't, doesn't.

Here are some recent rrd log entries, if that sheds any light.  "Mo" is 
the server with the graphs, "ws-1" is the one without:

rrd-data.log

Not sure what's going on here.
