Graphs stop update 24 hours after client reboot; start again 24 hours later.

Hi all,

I need some help/suggestions to figure out why my "cpu load" and "users
& processes" graphs stop updating about 24 hours after the systems
reboot. The updates stop for anywhere from 12 to 24 hours, then simply
start back up again.
Only the "CPU load" and the "Users and Processes" graphs are having the
problem; disk, memory, cpu utilization, network traffic don't miss a
beat.

We have a number of identically configured systems, they all reboot
around 00:30 local time (they are in different time zones) Wednesday
mornings. And they all stop reporting cpu-load/users-and-processes
graphs sometime Thursday mornings and then start up again Thursday
afternoon/Friday morning. They don't all stop/start at exactly the same
time, but the majority do stop/start at the same time.  I end up with
about a 24 hour gap in my graphs every week.

The rrd files are all updated except for the la.rrd, procs.rrd, and
users.rrd:

I've restarted the hobbit client and the hobbit server; no help.

Any pointers/suggestions would be very welcome!
