I wonder if it is a ndo issue... Run the following commands:

service nagios stop
killall -9 nagios
service ndo2db stop
service ndo2db start
service nagios start

Let us know if this fixed your problem.

I think the problem resides here:

'/usr/local/nagios/bin/ndomod.o' -> /tmp/nebmodVyRc5h

Is there anyway to change this to load to /export/tmp ?

Run the following command:

Code: Select all

chmod 777 /tmp

then restart the services again:

Code: Select all

service nagios stop
service ndo2db stop
service ndo2db start
service nagios start

Our CIS standards wont let things be execute from /tmp. Is there anyway to have this written to another directory and ran from there?
