[Ntop] Ntop crash!!

[simone cabib]

Hello,
I'm trying to run Ntop on redHat,
the host machine  is really powerfull, so I don't think this should be 
the problem
although I use Ntop on port mirroring on a quite large traffic net (ISP).
After few hours the application runs (as deamon) I get this message:

Attached are a big part of the log (with -t=7), and ntop.conf

Thank a lot,
