vSphere HA Auto Reboot

We have a VM migrated last May 17, 2017. It has critical service running. It reside in the same cluster and migrated successfully. 4 days later vSphere HA initiated a System Auto Reboot thus created a high business impact. Below is the log from vCenter Events.

"the virtual machine was restarted automatically by vsphere HA on this host. This response may be triggered by a failure of the host the virtual machine was originally running on or by an unclean power-off of the machine(eg. if the vm process was killed). The question is why it takes 4 days to vSphere HA issued Auto-Reboot?

Only that virtual machine restarted? No other virtual machine running on the same host restarted? Did you check the status of the host where the virtual machine was running?

There were other Servers as well on the other Host that got Auto-Rebooted by vSphere HA.

difficult to say without any logs / details / context. If you really want to know contact support. the FDM.log should provide all the details you need. I would be surprised if it took 4 days to responds. I suspect something else happened right before this reboot. but without all the logs it is difficult to say what caused this.
