Environment

VMware NSX for vSphere 6.3.x
VMware vSphere ESXi 6.0

Cause

This issue occurs due to race condition in dvfilter create/destroy events created by the virtual machine stuck in a reboot loop.

Resolution

This issue is resolved in VMware ESXi 6.0 Patch 04 (Build 4600944) and later releases, available at VMware Downloads.

To work around this issue if you do not want to upgrade, power off the affected virtual machine.

Additional Information
