I use removespikes.pl from the contribution of rrdtool to remove trafic spikes when routers etc. are rebooting.
This worked fine on opensuse 10.3 (perl v5.8.8) and os 11.2 (perl 5.10.0) but on os 11.3 (perl 5.12.1) it always says that there are no spikes even there are.
Using same rdd file to 10.3 will remove the spikes.

Nobody having the same issue? Any ideas, is there a math function bad???

Thanks for any hint
