hi list,
hoping someone could shed some light on this issue I just started seeing
today
all my compute nodes started showing as "Down" in the Horizon ->
Hypervisors -> Compute Nodes tab

if I stop and the start nova-compute on the down nodes the stop will take
several minutes and then the start will be quick and fine. but after about
2 hours the nova-compute service will show down again.
i am not seeing any ERRORS in nova logs.
I get this for the status of a node that is showing as "UP"

Does anything in the status messages show what could be wrong? What do the
"nova : TTY=unknown" messages mean?
thanks!!
