Does anyone know if 5.1 Update 1 resolves this issue? The release notes for update 1 mention:
"ESXi hosts might retain older version of the /etc/vmware/service/service.xml file after upgrade
When you modify the etc/vmware/service/service.xml, which has a sticky bit set, and then perform an ESX/ESXi upgrade from 4.0 to 5.1, the old service.xml files causes compatibility issues. This happens because the old service.xml file is retained by the ESXi host even after the upgrade.
This issue is resolved in this release."
