E-mail stopped working, duplicate and login is slow

[hausrocker]

Hi

I have a problem on my Nagios 3.5.0

Suddenly it stopped sending emails. No idea why and no idea how to check on that.
Does our exchange block that? Is that possible when nagios sends too many emails?

When I login to the system via ssh and putty or winscp it takes very long, like 5-10 tries before it connects. What could be the problem?

Also I get a message with:
Warning: Duplicate definition found for service 'Root Partition' on host 'localhost' (config file '/usr/local/nagios/etc/objects/localhost.cfg', starting on line 77)

But I searched in the file for "root partition", there is no second place where that is written.

HI @hausrocker

The duplicate shouldn't cause the email to stop. Check the Nagios logs for any errors calling the notation handlers, and then look at your mail logs for any errors as well.

Nagios Core is really efficient, so some process must be using too much CPU, I would run a top command to see if you can identify this. The other possibility is network congestion. Are you able to ping the Nagios server without issue?
