Configuration: vCenter Virtual Appliance running 5.1.0. 2 x identical ESXi hosts running 5.0U1. VCVA is running on ESXi host 'a'.
Symptom: vCenter complains of a disconnect in communication with the host, but automatically reconnects after a moment. ESXi hosts do not experience any issues - no reboots, no interruption to running VMs on them or connections to applications on the VMs. Have not been able to find any seemingly relevant messages in the logs on either ESXi hosts.
Times of events:
Oct 30, 3:07PM - disconnect from host 'b', automatically reconnected after a moment
Nov 6, 10:35PM - disconnect from host 'a', automatically reconnected after a moment
Nov 20, 8:00AM - disconnect from host 'a', automatically reconnected after a moment
The key errors that I've located are in the vCenter vpxd.log files. Same pattern of messages for each occurrence (didn't see these messagea at any other time).
Does anyone have any ideas as to what service is connecting to what, or where I might look for further information regarding this issue? I've not come up with any useful KB articles or discussion posts regarding these messages.
Any ideas would be appreciated!
