Your load on this Linux server is 885 with over 3000 concurrent processes, something is seriously wrong.
It is possible you may need to just reboot the server if it doesn't respond, but if you can get into the GUI, I would like to see a system profile from Admin -> System Profile

A very large portion of your CPU is being used by something called "OAS Manager" which is not part of Nagios.
However searching through some of the logs I did see several other issues, you are hitting the max connections to the database, set the following in /etc/my.cnf
under
add
Then restart mariadb
Also, you likely need more than 4 cores to handle all this processing.

A very large portion of your CPU is being used by something called "OAS Manager" which is not part of Nagios.
Code: Select all
PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND
12346 root 20 0 1772336 408976 6224 S 122.2 0.8 493:25.72 OAS Manager
As scott mentioned, the OAS Manager is still consuming a lot of your CPU.
You may also want to increase your kernel message queues.
Code: Select all
ndo2db: Error: max retries exceeded sending message to queue. Kernel queue parameters may need to be tuned. See README.
ndo2db: Warning: queue send error, retrying...
Follow this kb article to increase the values.
https://support.nagios.com/kb/article.php?id=139
Make sure to run these commands after making the changes:
Code: Select all
service nagios stop
service ndo2db restart
service nagios start
Once, that is done please show us the output of this:
