Please PM me another FRESH copy of your profile.zip as well so I can see the latest logs, that will give me more accurate information to go on.
Sorry about the delay, @ssax is out of the office and want to have you follow up and send the info and System Profile over so we can take a look at things.

So you're still seeing timeouts after the load issues have been resolved?
Send the output of these commands as root (I added another command):
ulimit -a
su -s /bin/bash -c 'ulimit -a' nagios
su -s /bin/bash -c 'ulimit -a' mysql
su -s /bin/bash -c 'ulimit -a' apache
netstat -s

The Nagios Answer Hub is a place where you can get help with technical questions from our experts. There, you can quickly open tickets and join discussion boards.
After completing the access form, you will be given access to a portal where new tickets can be created. We will keep the old customer forum sections and ticket system available for current cases to be resolved.
Let's go ahead and let things run for a bit and look at this again; revisit this on this in Answer Hub when we start to see things act up again. We definitely require attention to logging so we can dial any other optimizations in. However, looking over the history, I believe that we have implemented all optimal settings and configs.
Quoting a previous response. As we advance, the environment is tipping towards the max hosts and services that one server can efficiently handle. We recommended max is 20k; that is only a recommendation because it depends heavily on the type of service checks and the number of hosts, etc.
You can only do so much on a single XI server, you'll need to do what you can to mitigate the impact, but you should start looking at adding another XI server soon if you continue to experience load/kernel message queue/performance issues after doing the mitigation.
Let me know if you have any questions or if I can clarify anything.
Thanks,
Perry
