Nagios XI Memory usage growing

I have a test Nagios XI 2014 r2.0, posted about this server before, and noticed after a reboot the memory utilization is around 950mb. 4 days later it's at 2.1 gb.
I did a stress test on this box, some of you may have seen the thread on here, where I was doing 1138 checks per minute and It stayed solid around 2.4 gig on memory usage. I have since removed all those extra hosts and service checks down to only around 144 checks and 25 hosts. I did add check_smtp and check_SMTP_send checks to one mail relay server since then, runs every 5 minutes.
Just curious what could be going on. I did adjust the rescheduling intervals to adjust for the 1 minute checks and have not changed it back.. Most checks are 5 mins in my test environment now.
Here is a screenshot of my performance dashboard.. Just want to know if this is normal or do I have something set incorrectly, like the reschedule intervals, that is causing memory growth in a now smaller environment.

I believe there is a ndo memory leak. Our developers are working on the issue. I expect this to be fixed in the next release of XI.

I have tried to restart nagios and ndo2db but it does not affect the memory usage.
Is there another service I am missing that I can restart or just rebooting the machine altogher is needed?

Your memory usage doesn't look too bad but could you run the following command and post the results so we can look at the running processes?

Here you go. You could be right. This was about the same when I had put in about 350ish test hosts running checks on 1 min intervals..

Everything looks normal.
Do you have anymore details you can give us?

Honestly its a pretty standard install. Runs on RHEL 6 x64.. dedicated hardware ESX host with 24 cpus and 128 gigs of ram. The VM in that host is a 4 core 8 gig of ram. The raid this VM runs on does so on a 1.4 TB SSD array.
Not worried about performance, just the ram creep concerned me. What will it be like when we go full on production?

The disks are SSD in a raid. Server has VSPhere and ESXi as the OS so we can spin up servers as needed.

After disk buffers, your server is only using 775MB of ram.
1. Is this high for your server?
2. Does this value keep climbing?
3. Or is it just disk buffers? (which linux will aggressively allocate if the resources are available)
