VMware vSphere ESXi
This KB is applicable when one or more below mention factors are true.
The issue occurs under the circumstances described under cause. VMware is aware of this issue and is specific to VMware Tools version 10.x version.
This has been addressed in VMware Tools 11.
Workaround
For VMware Tools >= 10.3.5, installation of NSX Guest Introspection Drivers may cause tools to crash, which in turn could trigger this issue. Please refer to VMware Tools >= 10.3.5 crashes where NSX Guest Introspection driver are installed for information on that issue.
One way to prevent the problem is to set tools.upgrade.policy to manual for any guests running a version of tools earlier than 11.
