commands.conf entries (check_* commands). The full discussion I have had<br>
with more detailed notes is here:<br>
<br>
<a href="http://support.nagios.com/forum/viewtopic.php?f=7&t=8200" target="_blank">http://support.nagios.com/forum/viewtopic.php?f=7&t=8200</a><br>
<br>
One of the members suggested at this point I should post to the devel list.<br>
<br>
The short version is this. I am getting "Warning: Return code of 127 for<br>
check of service" in the nagios.log. After enabling debug logs I further<br>
ran the command manually as user nagios and it ran fine (no permissions<br>
errors or missing script as normal indicated by 127 error).<br>
<br>
End result seems to be the problem is max open files. Normally this<br>
would be fixed by increasing these in /etc/security/limits.conf for user<br>
nagios which we did (and rebooted). However this did not resolve the<br>
problem. I created a check script at that point to output ulimit -a and<br>
it repeatedly showed that the max was still 1024 even tho we had set it<br>
to a greater value.<br>
<br>
As I said, manually su'ing to nagios and running the script things<br>
worked fine. ulimit -a also showed the proper value. It seems to only be<br>
an issue when it is run from nagios.<br>
<br>
We are running on RHEL 6.2, using Nagios 3.4.3RC1, nagios-plugins 1.4.16.<br>
<br>
The full steps I took are listed in the support forums but if you have<br>
questions for me I would be more than happy to answer them. At this<br>
point I am at a loss as to what this could be.<br>
