Re: [hobbit] rrd error messages

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.

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.
