Auto reboot on Uninstall of MSI Package

Problem – the server reboots occassionally on uninstall of MSI package when it has not been asked to do so. I have not added any custom actions in Uninstall that would require this to be done and cannot find any other property configurations that seem to be requesting this either. Is there some error or condition under which this happens automatically? Is there a way to prevent this?

Here is the message from the Event Viewer:
