vCO gets outdated statistics from vCenter

Hi,

I'm trying to get host utilization statistics using the workflow posted here:

Get Host Effective Capacity

The problem is the returned information doesn't change on subsequent runs, even though showing changed on vCenter .

Tried disabling inventory service within /opt/vmo/app-server/server/vmo/conf/vmo.properties , but didn't help.

None of the following helped too:

esxHost.reload();

VcPlugin.refreshObjects(esxHost);

VcPlugin.refreshObjects(esxHost.parent);

Additional info:

vCO Appliance v5.1.1.0

vSphere v5.1.0u1

Hosts are part of a Cluster

Any help highly appreciated.
