[rrd-users] does rrd aberrant behaviuor detection really work ?

[Evan Miller]

The beta version of RRDtool does fix at least one known bug in the 
update logic, although I'm not sure it's the one that's affecting you. 
See this thread for more info:

https://lists.oetiker.ch/pipermail/rrd-developers/2007-August/002055.html

It's possible this bug was introduced between 1.2.15 and 1.2.19, but I'm 
not sure. It's also possible the bug you're seeing was fixed as part of 
more general code cleanup in the update logic. Anyway, glad it works in 
the beta version, at least.
