Some VMs got strange situation, show orphan , invalid or unknown status, but still online. I couldn't find any evidence why the VMs went to these status.

You have to upgrade to ESXi 5.1 latest version  or vCenter Server 5.1 update 1c  to permanent fix this problem. Workaround: Choose one option from follow
