After a recent vCenter migration we are seeing the following events in our cluster taks & events:
vCenter Server is connected to a master HA agent running on host ...
vCenter Server is disconnected from a master HA agent running on host ...
These two entries always appear together at just about the same time every 5 minutes. The server in question for each cluster is the master node.
vCenter Version / Build: 5.0.0 623373
Cluster Version / Build: ESX v4.1.0 (702113) / ESXi v5.0.0 (623860)
The clusters all appear to be functioning normally and the events are just info / warning - however it would be nice to get to the bottom of them. We recently migrated our vCenter instance to a new VM on a different subnet. We did go through and ensure that all of the hosts were properly disconnected / re-connected after the IP change.
I have started looking through the local logs on the master nodes in question and have found one entry that appears to align with the timing of the above events is:
vpxa.log:
2012-06-12T10:04:25.374Z [FFCBFAC0 error 'SoapAdapter.HTTPService'] HTTP Transaction failed on stream TCP(local=127.0.0.1:0, peer=127.0.0.1:61618) with error N7Vmacore15SystemExceptionE(Connection reset by peer)
I have read through some KBs regarding issues with DNS servers etc - I have confirmed that all DNS servers are reachable etc (this looks like the localhost address anyways...nost sure what DNS would do with that.)
Anyone see this? -- More importantly, anyone resolve this!?
