This error is an error from rrdtool related to the RRD format.
I don't see how we can do anything to affect this.

So if I delete the rrd files in question and let it recreate them and still get the same unable to parse header after they are created again would that rule out the rrd files being corrupted? Anything I can retrieve to help verify if this a bug in the stable branch or system? Problem is limited to Netscaler TCP graphs and Graphs -> Netscaler SSL graphs
netscaler-stats-tcp.rrd netscaler-SslStats.rrd
Thanks, Sam

This is likely because your rrd local files are corrupted.

So far I’ve only noticed it on specific Citrix Netscaler graphs, the Netscaler SSL ones nsSslHandshakes, nsSslSessions, etc and TCP Connections and TCP Packets for the netscalers are all in the same state with Unable to parse header `DSName'.

Sadly I didn’t notice when, I did recently upgrade to revision 8417, however these aren’t graphs I frequently look at. Anybody else with netscalers in their environment at the same revision?
