Just wanted to post stating we are seeing the exact same thing. we get the two alarms.
vmware-dadaservice-sca status changed from green to yellow which is concidered a critical alarm
we also get the warning vsphere-client status changed from green to yellow
if we reset to green within 1-2 min it will come back. I have noticed though that if i open only the web client and clear both of them and then open vsphere they pop up as soon as vsphere is done loading. has been since I updated to 6.0U1
when we were just on 6.0 we were getting the postrgress warning that they finally came out with a workaround which changed the time that it would check the database.
Something i was thinking about to maybe pinpoint the problem we did upgrade our 5.5 from a vmware image to an image from HP i wonder if any of the problems we are seeing are in relation to the drivers HP has in the image. anyone else with the warnings use an image from HP?
