I have one similar problem with FreeBSD 5.x and 4.x. Ntop works fine
one or two days when it suddenly gets a very high  CPU usage and the
daemon stops responding.

I've did some verification with ktrace/kdump in this high CPU
situation, and the results (filtered) where

#ktrace -p <NTOP PID>

# kdump -l | grep files
 20703 ntop     RET   accept -1 errno 24 Too many open files
 20703 ntop     RET   socket -1 errno 24 Too many open files
 20703 ntop     RET   socket -1 errno 24 Too many open files
 20703 ntop     RET   accept -1 errno 24 Too many open files
 20703 ntop     RET   socket -1 errno 24 Too many open files
 20703 ntop     RET   socket -1 errno 24 Too many open files
 20703 ntop     RET   accept -1 errno 24 Too many open files
 20703 ntop     RET   socket -1 errno 24 Too many open files
 20703 ntop     RET   socket -1 errno 24 Too many open files
 20703 ntop     RET   accept -1 errno 24 Too many open files
(...)

I've did some readjusting on FreeBSD kernel variables (kern.maxfiles,
kern.maxfilesperproc) but the problem still persists.
Even with maxfiles and maxfilesperproc adjusted to 60000, when
kern.openfiles gets ~1024, ntop goes to the scenario described.
Do I need to adjust maxusers too (now its 32, a reasonable number)?
Any tips are welcome.

Regards,
