I'm definitely no expert but...<br>* What does it say when you 'ldd' the nagios binary? Are all the libraries the binary is linked against able to be found? Are those libraries up-to-date?<br>* Where did you get nagios from? Did you compile it or is it pre-built? If pre-built, are there any updates?<br>
* I don't know Solaris well enough to know how to trace your running nagios with a very simple configuration, but that might be the next step. strace?<br><br><div class="gmail_quote">On 19 May 2010 10:49, nagios <span dir="ltr"><<a href="mailto:nagios@chadmail.com">nagios@chadmail.com</a>></span> wrote:<br>

Subject: [Nagios-users] SIGSEGV when trying to use eventhandler<br>
<br>
<div><font style="font-family: tahoma; font-size: 10pt;">
<div>Hi guys,</div>
<div> I am new to nagios but so far it's working well for me
and is monitoring a number of real and virtual hosts. Nagios 3.0.6 is
installed on an OpenSolaris 2009.06 host and monitoring routers other
devices and VM's in VirtualBox.</div>
<div> </div>
<div>My issue is when I try to add an event handler, I get a SIGSEGV and
nagios restarts.</div>
<div> </div>
<div> </div>
<div>I have posted the details of the code I am using and the error
here...<a href="http://pastebin.com/vBb7xTND" target="_blank">http://pastebin.com/vBb7xTND</a> and also below (but it reads better @
pastebin).</div>
<div> </div>
<div>I have tried several different scripts and code combinations (even
empty scripts and commands like ls) and all give the same error.</div>
<div> </div>
<div>Can anyone help me work out why it's happening?</div>
<div> </div>
<div>Thanks.</div>

too).<br>

As you can see from the below, it all works fine (ie. no SIGSEGV's) if
I comment out the eventhandler line from the hosts.cfg file.</div>
