Problem showing the virtualized machine information

I have installed the latest version of the hypervisor (rhev-hypervisor6-6.4-20130501.0.el6_4.noarch).

Update to this version, and it solved a bug which showed no rhevm information servers.

But today I found myself in a single hypervisor, which showed some servers information.

Missing one of the files:  /var/lib/libvirt/qemu/channels/srkmsaecnt01.com.redhat.rhevm.vdsm

Restarting the service vdsmd, recovers and displays the information in the rhevm.

This is a bug?
