Hi Henrik: Below are snippets from rrd that are still causing the "Duplicate Error" on my end, even after applying the patch. In the cases where there's netstat and ifstat data shown together, I had to include both because those chunks of data came out right at the time the duplicate error appeared. Too hard to time/see which of those 2 chunks of data cause the problem. In other cases, only ifstat data caused the problem. Where I have large chunks of whitespace- that separates "instances" of the duplicate error occurring. =========== @@data#348|1154533834.591188|192.168.224.202||wolf13.hmgc.mcw.edu|netsta t data wolf13,hmgc,mcw,edu.netstat linux Ip: 56731 total packets received 0 forwarded 0 incoming packets discarded 56067 incoming packets delivered 65344 requests sent out Icmp: 648 ICMP messages received 0 input ICMP message failed.
