You seem to have two instances of Nagios running.

Run these commands.

Code: Select all

service nagios stop
killall -9 nagios
service nagios start

After this, run this, and let us know the output.

Code: Select all

ps -ef | head -1 && ps -ef | grep bin/nagios

Looks like that cleared up.

How are the notifications? Still sending?

Posted: **Fri Dec 15, 2017 1:14 pm**

I have not received one since running those commands.

Is there anything I should or should not do to prevent this from happening again in the future?

Thank you for your assistance!

Glad to hear that it's working!

It's hard to say what may have caused two instances of Nagios to run in your case.

Usually, if I see something that isn't right in Nagios.

I always run this command, to check the nagios process.

Code: Select all

ps -ef | head -1 && ps -ef | grep bin/nagios

Otherwise, I'm glad I could help. I'll be closing this thread!

If you have any more questions, feel free to create another thread.

Thanks for using the Nagios Support Forum!
