Hello everyone.
I'm having an issue in my VmWare enviroment, we have a 3 hosts cluster configuration running on an HP BladeSystem C7000, Esxi 5.0.0 and VCenter.
Two days ago our first node tried to move the Vms to another node with no succes and after few minutes got disconnected from the cluster. Once rebooted it started working again correctly but i'm still getting the same error in VmKernel.log
All the nodes are running same hardware configuration, same firmwares and same software.. but we get these errors just in the first node.
