[Nagios-devel] nagios check_* and files limits

Postby Guest » Wed Dec 05, 2012 11:03 pm

I have been working to try and resolve a problem I am having with
commands.conf entries (check_* commands). The full discussion I have had
with more detailed notes is here:


One of the members suggested at this point I should post to the devel list.

The short version is this. I am getting "Warning: Return code of 127 for
check of service" in the nagios.log. After enabling debug logs I further
ran the command manually as user nagios and it ran fine (no permissions
errors or missing script as normal indicated by 127 error).

End result seems to be the problem is max open files. Normally this
would be fixed by increasing these in /etc/security/limits.conf for user
nagios which we did (and rebooted). However this did not resolve the
problem. I created a check script at that point to output ulimit -a and
it repeatedly showed that the max was still 1024 even tho we had set it
to a greater value.

As I said, manually su'ing to nagios and running the script things
worked fine. ulimit -a also showed the proper value. It seems to only be
an issue when it is run from nagios.

We are running on RHEL 6.2, using Nagios 3.4.3RC1, nagios-plugins 1.4.16.

The full steps I took are listed in the support forums but if you have
questions for me I would be more than happy to answer them. At this
point I am at a loss as to what this could be.
