Comment 1 Stephen John Smoogen 2018-10-09 21:39:46 UTC 
Do you have the nrpe-selinux rpm installed? If you do please do an audit2allow and see what might be stopping.
Comment 2 Mauricio Teixeira 2018-10-09 21:48:44 UTC 
I tried to install "nrpe-selinux" and the problem persists (nothing was logged to audit.log).
Comment 3 Stephen John Smoogen 2018-10-10 00:47:19 UTC 
Problem is one that should have been caught earlier and the package never been pushed to stable. This is on me.

The /etc/nagios/nrpe.cfg does not define the pid_file. It is left undefined and also points to the wrong place of /var/run/nrpe.pid

The systemd startup however needs the pid_file so that it can properly restart (and fix some other outstanding bugs). It wants it to be in /var/run/nrpe/nrpe.pid 

The fix will be define the correct entry in /etc/nagios/nrpe.cfg and restart nrpe. I will work on a fixed package and get it out as soon as possible.
Comment 4 Jeremy Christian 2018-10-12 15:51:55 UTC 
Stephen, this is causing headaches for my team and I, can you push the fix?
Comment 5 Stephen John Smoogen 2018-10-12 20:46:46 UTC 
The problem is trying to figure out why the fix was not included in the build as given. The configure script has a --with-pidfile assigned to the correct directory and it seems to do the right thing when I do a rpmbuild it was set up correctly without me doing any changes to the existing src.rpm

pid_file=/var/run/nrpe/nrpe.pid

However what came out of the build system does not have this. I am working through what could have caused this and hope to have a fixed package. It will however not fix any systems which have an edited /etc/nagios/nrpe.cfg Those will have a rpmnew and the old config won't have it.
Comment 6 Stephen John Smoogen 2018-10-12 21:01:43 UTC 
Please check to see if there is a /etc/nagios/nrpe.cfg.rpmnew in the systems. The boxes I found not working had an rpmnew from 2017 where the pid_file had been defined for the correct place. The change which seems to have broken was trying to fix another issue
