[Users] node loses contact with rhev agent

[Vinzenz Feenstra]

Hi,

Great to hear that you solved the issue. As a suggestion for next time:

Execute: service vdsmd restart on the node. You'll not loose your 
running VMs and it will work afterwards.
I think I managed to pinpoint the issue, however we're still trying to 
verify the patch I have implemented as a proposal for it.

I noticed that logs won't help me that much on that issue as this is 
some condition where the connection between host and guest times out due 
to the server being busy or something. I am not 100%ly certain about the 
cause, however the solution will be to reissue connects on time outs.

Regards,
