WARNING: RLIMIT_NPROC is 47285, total max estimated processe

We started noticing some intermittent weirdness with our Nagios XI 5.6.4 on CentOS 7 installation the other day. Pages won't completely load. Service checks won't show, but then will later on. General slowness.
Checking the event log I see this repeat every minute:
Code: Select all

I can't find that limit specified anywhere, and setting a higher limit in
/etc/security/limits.conf and/or
/etc/security/limits.d/20-nproc.conf don't seem to change that number, though the changes are reflected in
ulimit -a when run for both root and nagios users. Any idea what I'm missing?

I found this post that you can take a look at for increasing the NPROC setting in the systemd service file.
https://serverfault.com/questions/62861 ... n-centos-7
That warning may be a symptom of an another issue in the system from your description on how the interface is acting.
I would guess that there is a MYSQL database issue and to fully troubleshoot this, we would need to see the System Profile from the server.
To get your system profile. Login to the Nagios XI GUI using a web browser.
Click the "Admin" > "System Profile" Menu
Click the "Download Profile" button
Save the profile.zip file and upload it to the forum post.
Also, run the following commands as root and post the output here.
Code: Select all
echo "SELECT table_schema as 'Database', table_name AS 'Table', round(((data_length + index_length) / 1024 / 1024), 2) 'Size in MB' FROM information_schema.TABLES ORDER BY (data_length + index_length) DESC;" |mysql -t -u root -pnagiosxi
mysql -u root -pnagiosxi -e "show global status like '%used_connections%'; show variables like 'max_connections';"
Check the MariaDB log file to see if there are any errors at the bottom and post them here.

I'll have to wait on data extraction request from the security team since the server is in a secure environment. I did do a
tail -f /usr/local/nagiosxi/var/cmdsubsys.log and noticed that it keeps cycling through applying configurations. It never finds any problems with the configuration but reapplies every minutes or so:
Code: Select all
[root@cdeatlnagios01 ~]# tail -f /usr/local/nagiosxi/var/cmdsubsys.log

Try this, go to this menu Admin > Deadpool Settings, is it enabled?
If so disable it and see if the /usr/local/nagiosxi/var/cmdsubsys.log stops cycling through the Apply Configs.
If it is enabled, it is probably removing a host or service which is causing a bad configuration, then the system detects it, restores a good one.
Then the next time the Deadpool component runs, is does the same thing, removes the host or service and the process repeats forever.
The tables sizes don't look to bad. The statehistory table is large but on a larger busy system, that could be normal.
One thing I suggest, the Max Connections should be adjusted to a larger value to be safe in case that is the issue.
See this article for instructions.

That deadpool setting did the trick! Such a strange issue. I went ahead and make the recommended settings change to the max connections as a preventative measure. Thanks!
