Adding a few points
I agree with Eugen and what he said in his reply to your another email.
nova-compute log contains EHOSTUNREACH in connection to RabbitMQ, which indicates that there might be a problem with network connectivity.
I see you asked a few questions about Masakari in the list. In case you have Masakari or any other technologies to automate instance HA in that deployment, then I'd suggest you look into these components to check if automated evacuation was triggered or not.

This looks exactly same as the one seen in the list yesterday, and I see Eugen already gave you his insights.

What's the difference from the previous mail ? Could you explain what you additionally need now ?
I'd strongly suggest that you do not copy the same email to get more responses. If you need further help then being specific about your current problem may help people helping you. I'd also request you to be more patient and expect best effort basis response in mailing lists maintained by communities, in general.

Hello Team, I have an openstack environment with 4 compute Nodes however yesterday out of the blue, the Instances on one of the compute nodes started shutting themselves down. Then I realized the the compute service was disabled when I checked in Horizon. I enabled it and restarted the instances and all was well but I cant figure out what caused it. I have attached the nova_compute logs here incase someone would like to support
