I'm still getting these errors. Does no one have an answer? I have searched the archives and found nothing. They are occurring for multiple hosts and multiple services.
Thanks, Steve.

Greetings,
I am getting a lot of errors in the rrd-status.log file. There are 2 actually that are appearing at an alarming frequency (and have been for quite a while):
2007-05-21 09:42:52 RRD error updating /var/hobbit/data/rrd/client.purdue.edu/disk,export,video.rrd from 128.210.xxx.xxx: unknown consolidation function '^?<F8>'
2007-05-21 09:42:52 RRD error updating /var/hobbit/data/rrd/client.purdue.edu/memory.real.rrd from 128.210.xxx.xxx: illegal attempt to update using time 1179754972 when last update time is 2146959360 (minimum one second step)
Note that the system time on the hobbit server and on the clients are all synchronized with xntpd so the clocks aren't different.
I am also having some trouble with a lot of NAN values in the disk history graphs. I'm wondering a) how to fix these errors, and b) if the errors have anything to do with not getting good data in the graphs.
Thanks, Steve Holmes

This looks like a corrupted RRD file.

There are several potential reasons for this, but right now you should just take my word that it's harmless.

What's the load on your server ? I've seen this happen on my own system, where it turned out that the amount of RRD file-updates was pushing the disks beyond capacity. vmstat/iostat data usually picks this up. But then, this would affect all types of graphs.

Are you sure it's harmless in this particular case?? As a time value, that number evaluates to Tue Jan 12 19:36:00 2038. If the rrd has an entry with that datestamp, it won't accept new input for the next 30 years...

Thanks, Henrik.
There appear to be only 16 of the rrd files which might be corrupt. Is there any way to repair them, or am I stuck with just removing them?
There are no dates on the files further into the future than August of 2007. But that is more than one second off.
As to the server load. No the server isn't stressed at all.
Thanks, Steve.
