I have a VMWare 5 setup with 3 servers in the cluster. The system has been operating fine for months but currently my exchange vm has start rebooting nightly due to Vspheres HA.
Nothing changes in the setup that i'm aware of but now every morning i come in and vSphere has an alarm related to HA "Vsphere HA Virtual Machine monitoring action" and the exchange box has been restarted. the exchange box itself doesnt show any sign in the logs of service failure etc so I'm sure why HA is deciding to reboot the server every night.
Any advice would be helpful
