Comment 1 Barak 2014-10-21 12:29:10 UTC 
- is your system a stand alone (vdsm only ... no engine) ?
- did you actually run VMs ?
- did you install the host using host deploy or manually ?
Comment 2 Daniel Helgenberger 2014-10-21 14:19:56 UTC 
- is your system a stand alone (vdsm only ... no engine) ?
oVirt Hosted Engine

- did you actually run VMs ?
VMs are running. I can test without them, though

- did you install the host using host deploy or manually ?
Host was installed initially using hosted-engine-deply and updated using 'reinstall' from within engine
Comment 3 Daniel Helgenberger 2014-10-23 09:01:53 UTC 
Running no VMs on the hosts is yielding the same process growth rate (= has no effect):
