Problem Description
Ntop quits running after few minutes, with a Floating point exception.
I noticed the same behaviour with 2.1.55-1, but didn't investigate too much.Today I
upgraded to 2.1.57-0 and, having seen that ntop still crashes, used command line to
launch
ntop, so I was able to see the exception.
I use a standard RedHat Linux 7.3, with automake/autoconf from 8.0.I rebuild almost
every
package on my servers from source RPM.RRDTool is rrdtool-1.0.40-1.7.3 from
www.rrdtool.org.
