It looks like you have a couple of issues that have to be resolved.
The did not exit in a timely manner could be fixed by this KB article
https://support.nagios.com/kb/article/n ... anner.html

And the ndo2db errors could be fixed by this KB article.
https://support.nagios.com/kb/article/n ... eeded.html

If your system has a high number of host and service checks, that is one of the causes for the errors you are having and the above fixes should help out.

I have done the similar activity in past as well last month and there is no major integration after that nagios restart issue is fixed.

Below is my observation :
[root@nagiosxi var]# ipcs -q

------ Message Queues --------

0x03050002 3375104 nagios 600 35840 35

0xc9050002 3342345 nagios 600 5769216 5634

And still load average is too high on the server
[root@nagiosxi var]# uptime
03:09:33 up 20 days, 1:27, 3 users, load average: 47.14, 44.17, 45.24
Which is due to nagios application can you suggest how i can reduce the load average.

How many total hosts and services are you monitoring from this machine? With a load that high and the message queue issues you are seeing, I would imagine it is over 30k.

I have only 15060 services in total and there are around 168 nodes.

But would like to tell you that i have observer that as i restart nagios service from the GUI after some changes in configuration i observed increase in number of message q

current outoput
[root@nagiosxi ~]# ipcs -q

The current Message Queue looks pretty good when you posted.
Can you run the following command so we can see what are the top 20 processes are so we can start to look at what is causing the higher load? One quick thing you can do to gain some performance it to add a RAM Disk to the server.
The following are the instructions to setup that up on the Nagios server.
