OS is FreeBSD (5.4 i think?) and Nagios version is 2.0b4....not using any extra plugins or anything. <div>On 3/8/06, Marc Powell <<a href="mailto:marc@ena.com">marc@ena.com</a>> wrote: <blockquote class="gmail_quote" style="PADDING-LEFT: 1ex; MARGIN: 0px 0px 0px 0.8ex; BORDER-LEFT: #ccc 1px solid"> > -----Original Message----- > From: <a href="mailto:nagios-users-admin@lists.sourceforge.net"> nagios-users-admin@lists.sourceforge.net</a> [mailto:<a href="mailto:nagios-users-">nagios-users-</a> > <a href="mailto:admin@lists.sourceforge.net">admin@lists.sourceforge.net</a>] On Behalf Of Ryan Whalen > Sent: Wednesday, March 08, 2006 7:39 AM > To: <a href="mailto:nagios-users@lists.sourceforge.net">nagios-users@lists.sourceforge.net</a> > Subject: [Nagios-users] HOST ALERT: hostabc;DOWN;SOFT;1;Segmentation fault > > Last night I received three alerts from devices that were down.

What OS, plugin and nagios versions are you using? This could be interesting to troubleshoot. My feeling is that it's /bin/ping that is segfaulting when the site is down. I would have expected nagios to report a different kind of error if the plugin crashed (i.e. check of service foo on host bar did not exit properly). I think the only way you're going to be able to narrow it down is to try the check_ping command and using /bin/ping directly when you see this to see which it is. The only seemingly relevant mention I can find of a check_ping segfault is at the bottom of this thread -- <a href="http://64.233.179.104/search?q=cache:Svba1PNB27oJ:www.nagiosexchange.org"> http://64.233.179.104/search?q=cache:Svba1PNB27oJ:www.nagiosexchange.org</a> /nagiosplug-devel.31.0.html%3F%26tx_maillisttofaq_pi1%255Bmode%255D%3D1% 26tx_maillisttofaq_pi1%255BshowUid%255D%3D15650+nagios+check_ping+segfau lt&hl=en&gl=us&ct=clnk&cd=1&client=firefox-a Andreas Ericsson was troubleshooting a segfault issue but it isn't clear whether that was check_ping segfaulting or /bin/ping. Not much help I know but it's all I can offer. -- Marc ------------------------------------------------------- This SF.Net email is sponsored by xPML, a groundbreaking scripting language that extends applications into web and mobile media.
