Hi, It seems that ntop will start to consume 100% of the cpu after its ran for ~30 min. I have found some old information regarding this issue here: http://listgateway.unipi.it/pipermail/ntop-dev/2004-July/004747.html This article describes using the option --set-pcap-nonblocking as a work around, due to some sort of pthread issues. Indeed this option is specified in the startup script, however ntop's man page does not list any such options. Instead it has something similar called "--pcap_setnonblock", however attempting to start ntop with this option causes it to exit with sig 11: --- Nov 26 12:02:37 sniffer ntop[2956]: CHKVER: Version file is from 'version.ntop.org' Nov 26 12:02:37 sniffer ntop[2956]: CHKVER: as of date is '2004-03-22T04:30:00' Nov 26 12:02:37 sniffer ntop[2956]: CHKVER: This version of ntop is the CURRENT stable version Nov 26 13:43:40 sniffer ntop[2956]: CLEANUP: ntop caught signal 15 Nov 26 13:43:40 sniffer ntop[2956]: CLEANUP: Cleaning up, set FLAG_NTOPSTATE_TERM Nov 26 13:43:40 sniffer ntop[2956]: SIGPIPE: Handled (ignored) 0 errors Nov 26 13:43:40 sniffer ntop[2956]: CLEANUP: Locking purge mutex (may block for a little while) Nov 26 13:43:40 sniffer ntop[2956]: CLEANUP: Locked purge mutex, continuing shutdown Nov 26 13:43:40 sniffer ntop[2956]: FREE_HOST: Start, 1 device(s) Nov 26 13:43:40 sniffer ntop[2956]: FREE_HOST: End, freed 87 Nov 26 13:43:40 sniffer ntop[2956]: PLUGIN_TERM: Unloading plugins (if any) Nov 26 13:43:40 sniffer ntop[2956]: RRD: Locking mutex (may block for a little while) Nov 26 13:43:40 sniffer ntop[2956]: RRD: Locked mutex, continuing shutdown Nov 26 13:43:40 sniffer ntop[2956]: RRD: killThread() succeeded Nov 26 13:43:40 sniffer ntop[2956]: RRD: Thanks for using the rrdPlugin Nov 26 13:43:40 sniffer ntop[2956]: RRD: Done Nov 26 13:43:40 sniffer kernel: pid 2956 (ntop), uid 65534: exited on signal 11 --- I observed the same behaviour on a different machine, running FreeBSD 4.10. Also, every now and then ntop will not respond in the broswer interface when cliking on random links. P.S: Please include me in the replies, as i am not subscribed to the list. Thank you.
