Hello,<br><br>I use the program Cacti which uses rrdtool to provide graphs of data. I had a graph that Cacti was updating for me, but I wanted to add some historical data to it, generated by a script. I figured out a method to do this (create a new graph with [nearly] identical settings and then use rrd update to put in the historical data, following it by the new data pulled from the Cacti graph). However, when rrdtool tries to graph it with cacti's graph command for Yearly data I get an error and crash, which is different depending on what version I'm using. My server uses rrdtool 1.2.7 and it had a invalid pointer/memory corruption error and crashed. I tried the same procedure on my desktop using rrdtool 1.4.4 and got a Segmentation fault and no other information. <br>
<br>I'm not sure whether your mailing list takes attachments, so if you would just go to my cacti forum post <a href="http://forums.cacti.net/viewtopic.php?f=21&t=42206&sid=5b5ab88412533827bdbcf5785eb89510">http://forums.cacti.net/viewtopic.php?f=21&t=42206&sid=5b5ab88412533827bdbcf5785eb89510</a> there is a lot more detailed information, as well as the graph file(generated using the historical+new data) that is causing these issues. As you can see if you read the full thread, Gandalf(cacti developer) recommended that I report this issue as a bug on this mailing list.<br>
<br>Please let me know if there is anything I can do on my end to workaround and/or fix this issue, as my boss really wants that graph with historical data!<br><br>Thanks,<br>Chris Carpenter(mordocai)<br>
