Nagios Support Forum

I've installed Nagios, but when I try to start it from /etc/init.d/nagios reload or /etc/init.d/nagios start it ultimately fails. It occurs each time, "Caught SIGSEGV, shutting down...", within a few seconds of trying to start. I've reviewed the ownership of the directories and all are set to nagios:nagios for my nagios install at /data/local/nagios-4.1.

Output is as follows:

Anyone else experience this?

Can you tell us a bit about your environment?

After my initial install, I was able to successfully start nagios. I started it as a 'root' user even though nagios is owned by the user 'nagios'. When i checked for running services, numerous defunct processes were running too. I issued a 'kill -9 8486' on these defunct processes, attempted to stop nagios and start again. Processes have never started properly again since -- whether I try to start as 'nagios' or 'root'

The Sparc footprint isn't very big so it's unlikely that anyone else has ran across this yet, unless it's not a problem specific to 4.1

The best advice I'd have at this point is look through your compiler's output and see if there were any warnings or errors that sounded particularly discouraging. You could also turn debugging up in nagios.cfg and see if it offers any information - I don't think it will though.

There are some instructions on Oracle's site for building on Oracle Solaris - I'd look there for anything that applies.
