You may want to run one of the removespikes.pl or killspikes scripts. I
have seen this before especially with MRTG when e.g. a firewall is
restarted or similar. You need to act quickly before the Petabytes gets
into the averages.
Another note, before you run removespikes.pl make sure you back up all
your RRDs.
Good luck,
Vladimir

I'm running Ganglia 3.0.4 with the Power5 add-ons on AIX5.3
Bytes in and out statistics generally appear to have the right values.
However at random times, I get spikes in the petabytes/s range.
Here's a dump of the bytes_in database. At first, I suspected perhaps
these coincide with some counters getting reset, but they don't occur at
regular intervals.

Can anyone shed light on what might be happening? Any pointers for
debugging?
