Do you have any more of the debug or log output?

I would suggest:

1.) run in gdb to catch more info
or
2.) disable name/ip resolution (-n 0)

I'm currently working with someone to help identify this exact fault with 
regards to name/ip resolution.

Subject: [Ntop] Ntop crashing randomly.

Hi all,

I am experiencing and issue where ntop crashes at random intervals, sometimes 
it will run for a few days, sometimes it will crash every few hours. I am 
running ntop version 4.03 on centos 5.6 64 bit:
