Multiple instances of Nagios running, messes w/ web interfac

On a server running SLES11SP4 with Nagios Core 4.0.7, I am seeing multiple instances of Nagios running. I think that it's the cause of some messing with the web interface, causing hosts to blink in and out of view, some services to disappear, etc due perhaps to weird caching happening.

I've already checked out this topic of someone else on the forum running into >1 nagios instance running, though the solution presented there was just do an update from v3 to v4, which I'm already in. I'd appreciate any guidance/advice on where to look and how to better understand what's going on. Thank you!

You may want to upgrade to the latest version of Core as there could be some changes that could solve the issue that you are seeing.
https://www.nagios.org/projects/nagios-core/

How many hosts and services is the system monitoring?

How was this installation done? Do you have distribution Nagios RPM and source based Nagios install simultaneously? FWIW SLES Nagios rpm seems to give a lot of people trouble. Ideally you would start from a clean SLES and install from source.

Do multiple Nagios instances show up right after a boot?

Monitoring about 5 hosts, and 37 services. The workaround so far is that we restart Nagios, and then all is right in the world (accurate web pages, only one instance running). But given some time, eventually processes start piling up again, and the web interface is wrong again. I can't really update at the moment, but I could present that as a last ditch effort if this problem continues. I've done a complete reinstallation of the server already (testing a solution to another issue), and the problem persists.

If there are any resources regarding SLES, Nagios and the problems they can spawn together, please let me know.

Upon doing more research in the forums, the people who inquire about multiple instances running are usually told that the latest version of Nagios Core has additional checks in place to prevent it from happening (example here). Is there a changelog of sorts that points out where these checks were added? I'm interested to see why my install is missing them.

This is the changelog: https://www.nagios.org/projects/nagios-core/history/4x/
This is the repo: https://github.com/NagiosEnterprises/na ... gios-4.2.2

I doubt this issue has any relevance to the number of hosts or services. Generally this is caused by mixing and matching and altering Nagios installs. A source based install should only be upgraded via a source based upgrade and distro rpm install by distro rpm upgrade.

Also please post your nagios.cfg, by default this will reside in /usr/local/nagios/etc.

Since more than one issue which could be causing this were resolved in 4.2.0+ and that Nagios doesn't backport fixes, you basically have the following choices:
1. Do the backport (You, external dev, Nagios Enterprises)
2. Do the upgrade
3. Wait until you can upgrade.
4. Cron job a restart script.
