Well, I tried to duplicate the command that is showing up in the 'ps -xw' output, and it just hangs. [nagios@psdbsd01 (~)]$ whoami nagios [nagios@psdbsd01 (~)]$ su - nagios -c touch /usr/local/nagios/var/nagios.log /usr/local/nagios/var/retention.dat ^^ hangs here. In fact, if I just try to 'su - nagios' the process hangs as well. Using su with other parameters works, however, so the binary seems to function: [nagios@psdbsd01 (~)]$ su - Password: [root@psdbsd01 (~)]# And su - nagios from the root user appears to work fine. [root@psdbsd01 (~)]# su - nagios [nagios@psdbsd01 (~)]$ But su - nagios does not (as the nagios user): [nagios@psdbsd01 (~)]$ su - nagios ^^ hangs Sorry for all the noise. -- Eric Cables <div class="gmail_quote">On Thu, Jul 1, 2010 at 2:15 PM, Eric Cables <<a href="mailto:ecables@gmail.com">ecables@gmail.com</a>> wrote: <blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;"> Here are a few more details I've been able to gather.

I ended up rebooting the box, which fixed the problem temporarily, but it has resurfaced again. When I drill down into a service check it says that the next check will be processed at a time that has already passed. For example: Last Check: 13:09 Next Check: 13:11 The current time on, however, is 14:02... When I try to stop the process via the init script I get the following: [nagios@psdbsd01 (~/var)]$ /usr/local/etc/rc.d/nagios.sh stop Stopping nagios: .......... Warning - nagios did not exit in a timely manner The cmd file does not exist prior to attempting to start, after stopping, but I back to the problem where Nagios will not start and instead hangs indefenitely when requested to start. [nagios@psdbsd01 (~/var)]$ /usr/local/etc/rc.d/nagios.sh start Starting nagios: <-- hangs here I'm not sure about the lock file, this is a FreeBSD install from source, and I don't see a /var/lock directory at all. Everything Nagios related is installed in /usr/local/nagios as far as I can tell. There doesn't seem to be anything of interest in nagios.log, as the last entry just reports a notification that was sent out prior to Nagios losing its functionality. Any other tips? I'm not exactly sure why a reboot fixed this before, but any speculation is appreciated. -- Eric Cables<div><div></div><div> <div class="gmail_quote">On Thu, Jul 1, 2010 at 6:05 AM, Jim Avery <<a href="mailto:jim@jimavery.me.uk" target="_blank">jim@jimavery.me.uk</a>> wrote: <blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;"> <div><div></div><div>On 1 July 2010 01:18, Eric Cables <<a href="mailto:ecables@gmail.com" target="_blank">ecables@gmail.com</a>> wrote: > Sorry to bug the list, but my 3.2.1 installation of Nagios has all of a > sudden stopped starting.

Check you don't already have a nagios daemon running (ps -ef | grep nagios) before you start it again. Check that the lock file isn't there from the previous invocation (if you did a standard install from source tarballs the file is /var/lock/subsys/nagios). Check that the Nagios command file /usr/local/nagios/var/rw/nagios.cmd doesn't exist before you start nagios. Use full pathnames when attempting to verify your config, for example: /usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg <div><div></div><div> ------------------------------------------------------------------------------ This SF.net email is sponsored by Sprint What will you do first with EVO, the first 4G phone?
