>          Issue Type: Bug
>      Security Level: Public(Anyone can view this level - this is the

>          Components: VMware
>    Affects Versions: 4.1.0, 4.2.0

> When we turn on maintenance mode on one node of the cluster, the VMs are 
> migrating fine, but the host is never fully sent to maintenance mode on the 
> VMWare side.  We do see bunch of stack traces related to the management 
> server loosing connectivity, but machine will be available to ICMP for the 
> entire process. The host will appear as Disconnected. This is not a critical 
> issue (major tho) since the VMs are migrated properly, but the error should 
> be investigated/reproduced.
> See the attachments for logs.
