Theoretically this may be normal memory usage, Linux using free memory for the buffer cache. Can you instead show the output of "free", during one day, maybe run once per hour?

Sandro - Do you have available documentation that can support upgrading self hosted? I followed this http://community.redhat.com/blog/2014/10/up-and-running-with-ovirt-3-5/ Would it be as easy as installing the RPM and then running yum upgrade?

Thanks Sandro. Should clarify my storage is external on a redundant SAN. The steps I was concerned about was the actual upgrade. I tried to upgrade before and it brought my entire stack crumbling down so I'm hesitant. This bug seems like a huge bug that should at least somehow backported if at all possible because, to me, it renders the entire 3.5.6 branch unusable as no VMs can be deployed since OOM will eventually kill them. In any case that's just my opinion and I'm a new user to ovirt. The docs I followed originally got me going how I need and somehow didn't work for 3.6 in the same fashion so naturally I'm hesitant to upgrade but clearly have no option if I want to continue my infrastructure on ovirt. Thank you again for taking the time out to assist me, I truly appreciate it. I will try an upgrade next week and pray it all goes well :-) On Jan 23, 2016 12:40 AM, "Sandro Bonazzola" <sbonazzo(a)redhat.com&gt; wrote: > > > On Fri, Jan 22, 2016 at 10:53 PM, Charles Kozler <charles(a)fixflyer.com&gt; > wrote: > >> Sandro - >> >> Do you have available documentation that can support upgrading self >> hosted?

Sorry to be clear..the only way to resolve the memory leak I am facing now is to upgrade to el7?

Also the engine can stay running on el6 yes?

I successfully upgraded my engine to ovirt 3.6 in el6. Do I need to make my engine vm el7 too?

Thank you. I am in the process of upgrading my nodes to 7 although since the upgrade of my engine to ovirt 3.6 the network on the VM itself has become very instable. Ping packets are unresponsive from time to time and I cannot get a reliable SSH connection. My guess is something inside ovirt 3.6 does not like to run on a 3.5 node (expected I guess) and something is occurring inside of the brains somewhere. My hope now is to get my EL7 node up and running and hopefully join it to my cluster then start my hosted engine there On Mon, Feb 1, 2016 at 3:12 PM, Nir Soffer <nsoffer(a)redhat.com&gt; wrote: > On Mon, Feb 1, 2016 at 7:52 PM, Charles Kozler <charles(a)fixflyer.com&gt; > wrote: > > Sorry to be clear..the only way to resolve the memory leak I am facing > now > > is to upgrade to el7? > > If you want to use official packages, yes. > > But this is free software, so *you* are free to build your own package. > > The patches you need are in the ovirt-3.5 branch: > https://github.com/oVirt/vdsm/tree/ovirt-3.5 > > You clone vdsm, checkout this branch, and build it.
