I have three ESX Host and all are running without errors, however every now and then I get a Host esx1.rapa.local in RAPA DC is not responding. I get this within my events and it's happening to all my ESX Host (esx2.rapa.local and esx3.rapa.local). I do not know why it's losing connection to host and it happens very fast and connects back to all host. I haven't received any complaints that the network was down, but it's making me worry.
Thanks for your help and support.
