Hi luca,
I would love to but I am pretty new to ntop. If you could give me some instructions on how to debug, I would appreciate that.
Thanks,

Dear all,
I am having same problem as Chor Keung Li had. I got ntop from SVN, version 3.3.11-dev. Everything worked fine until I turned on sflow plugin. Same error message.
Li, do you got the problem fixed? Deri, you replyed on July 3rd, 2009 saying the svn version had the new fix, but I guess it is not working still...
BTW, I am running centos 5.
Originally messages:
I have made a fix for sFlow in the ntop code in SVN. Please download it
and check if it works.
