I can confirm the latest packages upgrade fixes this issue.

I don’t think there is a graceful path to downgrade.There is a hot fix upstream I believe. My understanding is the build is being tested for release.Francois Lafont posted in the other thread:Begin forwarded message:From: Francois Lafont <francois.lafont.1978@gmail.com >Subject: Re: 10.2.4 Jewel releasedDate: December 9, 2016 at 11:54:06 AM CSTContent-Type: text/plain; charset="us-ascii"On 12/09/2016 06:39 PM, Alex Evonosky wrote:Sounds great. May I asked what procedure you did to upgrade?
Of course. ;)
It's here: https://shaman.ceph.com/repos/ceph/wip-msgr-jewel-fix2/
(I think this link was pointed by Greg Farnum or Sage Weil in a
previous message).
Personally I use Ubuntu Trusty, so for me in the page above leads me
to use this line in my "sources.list":
deb http://3.chacra.ceph.com/r/ceph/wip-msgr-jewel-fix2/ trusty main5d3c76c1c6e991649f0beedb80e682 3606176d9e/ubuntu/trusty/ flavors/default/
And after that "apt-get update && apt-get upgrade" etc.

I just retested and it is exactly 15 minutes when the load starts to climb.So, just like Diego, do you know if there is a fix for this yet and when it might be available on the repo? Should I try to install the prior minor release version for now?Thank you for the information.Have a good day,Lewis George

It has 24 OSDs. Everything looked okay during the initial build and I was able to run the 'rados bench' on it just fine. However, if I just let the cluster sit and run for a few minutes without anything happening, the load starts to go up quickly. Each OSD device ends up using 130% CPU, with the load on the box hitting 550.00. No operations are going on, nothing shows up in the logs as happening or wrong. If I restart the OSD processes, the load stays down for a few minutes(almost at nothing) and then just jumps back up again.Any idea what could cause this or a direction I can look to check it?Have a good day,Lewis George_________________
