[mrtg] Graphs Resetting & Freezing

[Matt Baer]

I'm having a real problem with this particular MRTG installation.  I came in
to work this morning and found that a half dozen of my graphs reset just
before 6AM and that two of them froze at some point over the weekend.  The
graphs that I'm having trouble with are a mix between direct OID polls and
scripts.  Two of the ones that reset were directly configured with cfgmaker.

Here is the portion of the logfile that pertains to one of the graphs that
reset:

The "routers" mentioned are scripts that are set up to monitor the amount of
SPAM blocked  and e-mails rejected by our e-mail server.  Those two are the
ones that are frozen in time.  But there is no mention of the graphs that
were reset.  Anyone have a clue where I can start troubleshooting these
issues?
