Hi all, I have finally identified another cause of excessive CPU usage on freeBSD. I don't know why, but when ntop calls gethostbyaddr() for resolving IP addresses, if the DNS does not reply (I have a DNS on Linux and sometimes it does not reply at the first try for some addresses), gethostbyaddr() loops (or similar), allocates memory and then ntop uses all the CPU and no more addresses are resolved. Hence I assume this is a bug of gethostbyaddr() on FreeBSD. I cannot use signals (like my other apps do) for overcoming the problems, as ntop is multithreaded. In the meantime (until the FreeBSD community fixes the bug), addresses are resolved using /usr/bin/host via a pipe. Thanks to the patch, ntop memory isn't growing as it used to be and CPU usage is rather low. Now I can finally go back to my mailer: I have so many unanswered mails.
