we have 2 esxi 4.1 hosts running which loose connectivity intermittently when connected with various clients - vsphere client, FastSCP or VM Explorer. This prevents us to back up VMs.
From vsphere client we get the following message:
The request failed becuase the server '192.168.0.6' closed the connection. (The underlying connection was closed: A connection that was expected to be kept alive was closed by the server.)
Call "PropertyCollector.CreateFilter" for object "ha-property-collector" on ESXi "192.168.0.6" failed.
The problem disappears if we shut down one host, we can backup VMs with trilead or FastSCP without issues.
Any insight will be appreciated.
