Can not ping the vm guest in Esxi 5.1

Hi all

    I have a Vcenter version 5.5 and 2 Esxi 5.1 joined, recent I have an issue with one of the Esxi host, this Esxi host and 4 vm guests running, suddenly I couldn't ping any of the vm guest in this Esxi host, but I could ping this Esxi host, but won't be able to connected via vsphere client, in order to have this resolved is to reboot the Esxi host itself, any idea what causes such problem ?

So are ALL your virtual machines and ESXi host on the same 10.0.0.40 network ?

if you cannot connect via vSphere Client to 10.0.0.40 - the network management agents have hung, or crashed.

Are you trying to connect directly, or is this via vCenter Server ?

This would still allow you to ping the management interface, on 10.0.0.40, but something must be affecting the vSwitch.

Can you re-produce the issue ?

I notice you are on the latest version of 5.1, but your ESXi host is not setup correctly, e.g. localhost.localdomain ?

this should have a hostname, and FQDN ?

You also have only a single interface, which is a single point of failure.
