CS 4.4.1 - 4.4.2 I am having a problem with my xenserver hosts getting stuck in maintenance. Trying to cancel the maintenance produces the following NPE.

I think it started in 4.4.1 because it used to work properly in 4.4.0. I also deleted and re-created the SSVM but that did not help either. Does anyone have a solution or workaround? Is there a way to manually take a host out of maintenance? I think there is more to it than setting the status in the DB? — Steve
