I downloaded the OVF and deployed to my home VM server to do some testing. I did nothing to it what so ever and it has high load. I finally was able to login during one of the high load periods and do a top:

What the heck could this be doing? The only thing it is monitoring is localhost. After seeing this issue, I did run a yum update and the problem persists. It shouldn't be my VM host, it has 8 XEON 2.4Ghz cores and 64GB of memory and this is the only VM running on it at the moment. It's a true server class server, an HP DL360G5.

EDIT: Looking at another post, they are having similar issues every 7 hours. Looking at my charts it seems about every 11 hours for me. I was trying to look at it but my load was 27, I couldnt use the server, I had to restart.

Trevor is working on reproducing this.
Were you using the 64bit ovf?
What XI version? 2014r1.1?

64-Bit 1 CPU 2 Cores 8GB Ram.

Yes, version 1.1.

I have added a second CPU and also moved vm host(yes I have a farm at home) and the issues seems to be much better. I will move it back to the other host and see if it happens again, just to rule out my host for sure.

Just downloaded 2014r1.1 64-bit OVA, no load problems so far. Did not log into XI interface, literally just logged in as root and ran top. Am I missing anything that you did?

Let it sit for a day

Posted: **Mon Jun 16, 2014 11:42 am**

I figured as much, just didn't want to have it sit only to find out I did something differently.

Check this out:

I know this isn't actually high anymore(it was close to 30 when I opened thread), but it seems to be on a pretty regular about 7 hour interval like WillemDH mentioned in his post here: http://support.nagios.com/forum/viewtop ... 16&t=27708

All mine is doing is localhost checks and whatever else was in the image provided. Not sure what would be happening every 7 hours to cause spikes. My issue since the upgrade on 2 of the servers are now show high I/O wait every so often as well, and both of these servers never showed any sign of this before the upgrade to 2014. I know I'm throwing a bunch of stuff out, just babbling to make sure I get everything out that I can before Wednesday

I just updated one of my 2014 1.0 VM's to 1.1 I'm going to jump on the troubleshooting bandwagon and see if I have the same result as you two after 7-11'ish hours. I had an initial 1 minute load average about .80 or so above where it was at version 1.0 but that has since dropped much lower.

That looks unfortunately quite similar to my results:

As I said in the other thread with Willem, this is something we can look into since we've got it replicated in-house.

Trevor, lock this up since its a dupe with Willem. No need to track two threads and his was first.
