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.
