these are all vcenters, multiple versions (4.1, 5.0 and 5.1)
its really odd that i can use Get-VM on the same server that it claimed disconnection with no errors, something like this:
1) Connected to 3 vCenters: vc01, vc02 and vc03
2) Run script and i get the error 'vc01 is not connected'
3) Get-VM vm01 (which happens to be at 'vc01', that just disconnected) and it retrieves it normally
edit:
ran the command with the modifications to troubleshoot disconnection like you said, and no disconnections at all ! All the 15 vCenters still connected while running the command
The exception is below
Get-VIObjectByVIView : 25/09/2013 11:25:27 Get-VIObjectByVIView Server XXXXX is not connected.
