Hello there,

I am having a lot of problems with nova compute,  after 30 minutes all my
computes report XXX when I execute nova-manage service list



So I restart rabbitmq and conductor in the controller node, libvrit-bin and
nova-compute in all the compute hosts and everithing return OK but 30
minutes after all the computes goes XXX again.

I noticed that nova-compute, libvirt-bin are ok in thoose hosts and the
rabbitmq server is alive but I still have XXX witth nova-manage servce list.

I am using ubuntu 14.04 and Icehouse release. I noticed too this in the
rabbitmq log:
